Neuroanatomy Practical Flashcards
Amygdala
Fear, reward, salience
Anterior Commissure
Minor connection between the hemispheres
Basal Ganglia
Habit learning, reward learning
Caudate Nucleus
Movement, habit learning, reward learning
Central Sulcus
Divides the frontal lobe from the parietal lobe
Cerebellum
Fine movement
Cerebral Aqueduct
Distributes cerebral spinal fluid from 4th ventricle, under inferior
colliculus, and to third ventricle
Cerebrum
All outer gray matter
Cingulate Gyrus
Social valuation, conflict monitoring
Cingulate Sulcus
Sulcus above the cingulate
Claustrum
Attention, awareness
Corpus Callosum
Major connection between the hemispheres
Fornix
Connects the hippocampus to the mammillary bodies
Fourth Ventricle
Distributes/stores/produces cerebral spinal fluid under the cerebellum
Frontal Lobe
Goals and how to achieve them
Genu
Front of the corpus callosum
Globus Pallidus
Smooth voluntary movement
Gray Matter
Cell bodies
Gyri (Gyrus)
Bulges in the cortex
Hippocampal Gyrus
Memory
Hippocampus
Memory, navigation
Hypothalamus
Regulates hormones to connect the nervous system to the endocrine
system
Inferior Colliculus
Hearing
Insula
Disgust, empathy
Lateral sulcus
Separates the temporal and frontal lobes
Lateral Ventricle
Distributes/stores/produces cerebral spinal fluid
Limbic System
Emotion
Longitudinal Fissure
Sulcus that separates the hemispheres
Mammillary Bodies
Memory
Medulla Oblongata
Autonomic functions (breathing, heart rate, etc)
Occipital Lobe
Vision
Olfactory Bulbs
Smell
Optic Chiasm
Where visual signals cross over
Optic Nerve
Transmit visual signals from retina to chiasm
Optic Tracts
Transmit visual signals from chiasm to V1
Orbitofrontal Cortex
Goal directed behavior, decision making
Parietal Lobe
Metrics about where/how-many things there are
Pineal Gland
Produces melatonin, sleep, circadian rhythm
Pituitary Gland (infundibulum)
Hormone regulation (growth, energy regulation, sex hormones, etc)
Pons
Automatic actions (respiration, reflexes, swallowing, etc)
Posterior Commissure
Minor connection between the hemispheres
Primary Motor Cortex
Motor homunculus
Primary Somatosensory Cortex
Sensory homunculus
Putamen
movement, learning
Pyriform cortex (uncus)
Smell
Retrosplenial cortex
Memory
Rhinal Cortex (entorhinal & perirhinal)
memory
Rhinal Fissure
Separates the pyriform cortex from the temporal lobe
Septum Pellucidum
Separates lateral ventricles
Spinal Cord
Connects brain to body
Splenium
Back of the corpus callosum
Sulci (Sulcus)
Wrinkles in the cortex
Superior Colliculus
Vision
Temporal lobe
Memory, audition, speech
Thalamus
Central transit hub for sensory signals
Third ventricle
Distributes/stores/produces cerebral spinal fluid around the thalamus
