antipsychotics are associated with movement, intelligence, abstract thinking, the ability to organize, personality, behavior, and emotional control. Traumatic brain injuries can result in personality

changes, difficulty controlling emotions, and other cognitive functions - CORRECT

ANSWER >>> Frontal Lobes

responsible for proprioception, is the home of the somatic senses. This part of the brain helps a person to identify spatial relationships, interpret pain and touch in the body, and identify and

give meaning to objects - CORRECT ANSWER >>> Parietal Lobe (Middle Brain)

Damage to the anterior portion may cause asterogenesis, the loss of ability to recognize objects via the sense of touch. This may be experienced by patients with post cerebral vascular

accidents - CORRECT ANSWER >>> parietal Lobe

and involved in short-term memory, speech, auditory signals, and smell recognition. It identifies "what" things are - object identification. It contains the limbic system, amygdala, and

hippocampus. - CORRECT ANSWER >>> Temporal Lobe

Disorders from this lobe include dementia, affective disorders, and attention deficit

hyperactivity disorders (ADHD). - CORRECT ANSWER >>> Temporal Lobe

- CORRECT ANSWER >>> Dorsal striatum

This is involved in the reward circuit and reinforces addictive behaviors. - CORRECT

ANSWER >>> Nucleus accumbens

This is associated with pleasure, reward, and reinforcing behavior. Drug abuse affects the limbic

system, disrupting emotions and feelings associated with normal behavior. - CORRECT

CORRECT ANSWER >>> Negative symptoms

If the functioning of this pathway is disrupted by lesions or drugs, prolactin levels can also rise. Elevated prolactin levels are associated with galactorrhea (breast secretions), gynecomastia (enlarged breasts especially in men), amenorrhea (loss of ovulation and menstrual periods), and

possibly other problems such as sexual dysfunction. -^ CORRECT ANSWER

>>> tuberoinfundibular DA neurons

Projects from the midbrain VTA but sends its axons to areas of the prefrontal cortex, where they may have a role in mediating cognitive symptoms (dorsolateral prefrontal cortex or DLPFC) and

affective symptoms (ventromedial prefrontal cortex or VMPFC) of schizophrenia. - CORRECT

ANSWER >>> The mesocortical dopamine pathway

which projects from the substantia nigra to the basal ganglia or striatum, is part of the

extrapyramidal nervous system and controls motor function and movement. - CORRECT

ANSWER >>> Nigrostriatal dopamine pathway

projects from the midbrain ventral tegmental area (VTA) to the nucleus accumbens, a part of the limbic system of the brain thought to be involved in many behaviors such as pleasurable sensations,the powerful euphoria of drugs of abuse, and delusions and hallucinations of

psychosis. - CORRECT ANSWER >>> mesolimbic dopamine pathway

What are the three major hypotheses of pychosis? - CORRECT ANSWER >>> The Dopamine

theory, the Glutamate theory, and the serotonin theory. Treat both positive and negative signs of psychosis. They are considered serotonin-dopamine antagonists, as they maintain D2 antagonism but also have simultaneous serotonin 5HT2A antagonism. Serotonin (5HT) can regulate DA release directly or indirectly, producing various effects on dopamine (DA) neurons. 5HT1A and 5HT2A receptors have opposite actions on dopamine release. Stimulation of 5HT1A receptors increases dopamine release (a DA accelerator). Once bound to 5HT1A receptors, 5HT causes inhibition of its release, which results in increased dopamine

output. - CORRECT ANSWER >>> SGA 'atypical'

When people dont have enough of this neurotransmitter, they may experience anxiety or even schizophrenia. Some meds use this neurotransmitters benefits to help people sleep for medical

procedures. - CORRECT ANSWER >>> Gaba

am also a monoamine neurotransmitter and I serve many functions in the human body. Do you remember learning about flight, fight, or fright? That's me, in excess. A little of me can get you up off the couch and have you alert, oriented, and ready to take on life's challenges. I can really

help with focus and productivity which is why you see me with a cup of coffee. - CORRECT

ANSWER >>> Norepinephrine

too much can cause antsy, nervous, and affect your ability to focus -^ CORRECT ANSWER

>>> Norepinephrine

one of the key neurotransmitters that psychotropic drugs target. Within the central nervous system, I affect arousal, motivation, attention, learning, and REM sleep. I work within the

parasympathetic nervous system too. I can make you sweat and salivate. - CORRECT

ANSWER >>> acetylcholine

Substances that block me can paralyze you because I am the link between the brain and muscles. When there's not enough of me, I can be involved in Alzheimer's and Parkinson's disease. Increase me, and I can help with symptoms, but be cautious, because I also have a role in addiction. Dr. Stahl refers to me as "the brain's own nicotine" when he talks about my role in

addiction. - CORRECT ANSWER >>> acetylcholine

I help to regulate mood. I've been called the "happy hormone," but actually I am not a hormone at all; I am a monoamine neurotransmitter. Your body synthesizes me naturally from

tryptophan. I help to regulate sleep, arousal, libido, aggression, and pain perception. -

CORRECT ANSWER >>> serotonin ( 5HT )

I am one of the key monamine neurotransmitters that regulate mood. I am associated with executive function, your ability to perform well, be organized, and all those good things including emotional intelligence. That's when I'm working hard in the prefrontal cortex. I'm also essential to your movement and coordination. Being balanced is very important to me; too

much or too little can cause problems. - CORRECT ANSWER >>> Dopamine

When my levels are low you'll lose pleasure, interest, alertness, and even self-confidence. Low

levels are also found in clients who have Parkinson's disease. -^ CORRECT ANSWER

>>> Dopamine

Too much of me is not always a good thing. I can lead to the hallucinations you see in schizophrenia and psychosis. Another thing, do you know that great feeling you get when you

win something? That's me, at work in your reward center. -^ CORRECT ANSWER

>>> Dopamine

Some people have trouble with me because my reward properties can lead to all types of

addictions. - CORRECT ANSWER >>> Dopamine

amino acid and THE excitatory neurotransmitter. I've been referred to as the workhorse of the brain because I can affect almost every neuron in the brain. I'm quite the firecracker. You'll find me working hard all over the brain affecting energy, memory, learning, and neural plasticity. I

also work to relay sensory information and regulate spinal and motor reflexes. - CORRECT

ANSWER >>> glutamate

When my levels are too high, I've been associated with schizophrenia, epilepsy, and mania. -

CORRECT ANSWER >>> glutamate

This is involved in the reward circuit and reinforces addictive behaviors. - CORRECT

ANSWER >>> Nucleus Accumbens

A group of structures involved in voluntary motor movements, cognition, and emotion. movement disorders include Parkinson's disease, obsessive-compulsive disorder (OCD), and Tourette syndrome. The striatum is a group of structures that includes the caudate, putamen, and nucleus accumbens. The dorsal striatum contains the caudate nucleus and the putamen. The ventral striatum contains the nucleus accumbens. Both are involved in facilitating voluntary

movement. - CORRECT ANSWER >>> Basal Ganglia

This is an egg-shaped structure involved in sensory organ and motor command processing. All sensory systems except for the olfaction process through this, which is responsible for processing all external information. Has been associated with symptoms related to

schizophrenia and post-traumatic stress disorder (PTSD). - CORRECT ANSWER >>> thalamus

This is involved in complex motor actions and linkage of cognition to motor actions. It is the main input area for the basal ganglia and is activated when anticipating or engaging in pleasure.

- CORRECT ANSWER >>> Dorsal Striatum This controls the communication between the two brain hemispheres. Is involved in attention, impulse control, and emotion regulation. It integrates impulses from both sides of the brain.

Persons with an underdeveloped or missing _____ may have intellectual impairment. -

CORRECT ANSWER >>> The corpus callosum

Is located on the sides of the brain and involved in short-term memory, speech, auditory signals, and smell recognition. It identifies "what" things are - object identification. It contains the limbic system, amygdala, and hippocampus. There are multiple pathways within this which affect object identification and language comprehension, including the ability to understand semantics. A dominant __________ lesion can present as Wernicke's aphasia. Disorders of this structure include dementia, affective disorders, and attention deficit hyperactivity disorders

(ADHD). - CORRECT ANSWER >>> temporal lobe

This is the back part of the brain and controls visual processing. Damage to this lobe results in the inability to form visual memories. Bilateral lobe damage results in the inability to recognize items by sight even though vision is normal. seizures of this lobe can cause hallucinations, such

as lines of color. - CORRECT ANSWER >>> Occipital lobe

Are associated with movement, intelligence, abstract thinking. the ability to organize, personality, behavior, and emotional control. Traumatic brain injuries can result in personality

changes, difficulty controlling emotions, and other cognitive functions. - CORRECT

ANSWER >>> Frontal Lobes

The middle part of the brain, responsible for proprioception, is the home of the somatic senses. This part of the brain helps a person to identify spatial relationships, interpret pain and touch in the body, and identify and give meaning to objects. Damage to the anterior portion of this lobe may cause asterogenesis, the loss of ability to recognize objects via the sense of touch. This may

be experienced by patients with post cerebral vascular accidents. -^ CORRECT ANSWER

>>> parietal lobe

imbalance of this because it can impact human emotion and behavior. - CORRECT

ANSWER >>> Neurotransmitters

alertness, and even self-confidence. Low levels are also found in clients who have Parkinson's disease. Too much of me is not always a good thing. I can lead to the hallucinations you see in

schizophrenia and psychosis. - CORRECT ANSWER >>> Dopamine

I've been referred to as the workhorse of the brain because I can affect almost every neuron in the brain. I'm quite the firecracker. You'll find me working hard all over the brain affecting energy, memory, learning, and neural plasticity. I also work to relay sensory information and regulate spinal and motor reflexes. When my levels are too high, I've been associated with schizophrenia, epilepsy, and mania. My receptors, NMDA and AMPA, work with me across many

regions of the brain. I can really make things happen. - CORRECT ANSWER >>> Glutamate
