Anatomy & Research Methods: Anatomical Directions in the Nervous System, Slides of Biological Psychology
A comprehensive overview of anatomical directions in the nervous system, covering key structures like the spinal cord, brain, and cerebral cortex. It delves into the functions of different brain regions, including the hindbrain, midbrain, and forebrain, and explores research methods used to study the brain, such as brain damage, stimulation, and recording brain activity. The document also emphasizes the importance of ethical considerations in research involving non-human animals.

ANATOMY & RESEARCH METHODS
CHAPTER 3
ANATOMICAL DIRECTIONS IN THE
NERVOUS SYSTEM
THE SPINAL CORD
Part of CNS found within spinal
column
(^) Communicates with sense organs & muscles (except head) (^) Entering dorsal roots carry sensory information (^) Exiting ventral roots carry motor information
THE SPINAL CORD
Two types of matter
(^) Grey matter: located in center of spinal cord (^) densely packed with cell bodies & dendrites (^) White matter: mostly myelinated axons that carry info from gray matter to brain/other areas of spinal cord
Each segment sends sensory information to brain & receives
motor commands
THE SYMPATHETIC NERVOUS SYSTEM
Network of nerves prepares organs
for rigorous activity
(^) Increases heart rate, blood pressure, respiration… (^) “fight or flight” response (^) Mostly uses norepinephrine
EXAMPLE: DIVISIONS OF A FISH & HUMAN BRAIN
THE HINDBRAIN
(^) Medulla (^) Pons (^) Cerebellum
The Human Brainstem
THE HINDBRAIN—THE PONS
(^) Lies on each side of the medulla (^) Axons from each half of the brain cross to the opposite side of the spinal cord (^) Cranial nerves
THE HINDBRAIN—THE CEREBELLUM
(^) Helps regulate motor movement, balance, & coordination (^) Learning & conditioning
SAGITTAL SECTION THROUGH THE HUMAN
BRAIN
THE FOREBRAIN
Most anterior & prominent part of mammalian brain
2 cerebral hemispheres
Outer cerebral cortex & subcortical regions
Contralateral processing
THE FOREBRAIN—SUBCORTICAL REGIONS
Structures underneath cortex
(^) Thalamus: (^) Relay station from sensory organs (^) Main source of input to cortex (^) Hypothalamus: (^) Conveys messages to pituitary gland to alter release of hormones (^) Motivated emotions - eating, drinking, sexual activity,
Together form “diencephalon”
THE FOREBRAIN—THE PITUITARY GLAND
AND BASAL GANGLIA
Pituitary gland: hormone-producing
gland found at base of the
hypothalamus
Basal ganglia: includes caudate
nucleus, putamen, and globus
pallidus
(^) Planning motor movement & aspects of memory & emotional expression (^) Attention, language planning, & learning over time
