Cerebrum Flashcards
Hypothalamus
Integrates behaviors with visceral functions
Maintains homeostasis
Regulation of circadian rhythms
Endocrine regulation
Epithalamus - Pineal Gland
endocrine glad, helps regulate circadian rhythms
Subthalamus
BG nucleus, facilitates output nucleii
Limbic System Function
Emotions and behavior, memory
Limbic System Structures
hypothalamus, hippocampus, amygdala, insula, basal forebrain
Thalamus
Regulate activity level of cortical neurons. Has 3 groups of nucleii (anterior, medial, lateral)
Relay Nuclei
info from sensory systems, BG, and cerebellum to cortex
Association Nuclei
Emotional memory info
Non-specific nuclei
consciousness, arousal, attention
Cerebral Cortex Layers
Neocortex: 6
Archicortex: 3
Archicortex
Olfactory
Medial Temporal
-Limbic system
-Hippocampus
Unimodal
secondary sensory, further processes a specific sense
Heteromodal
association cortex - higher order processing, integration of information
Frontal Eye Fields
initiate voluntary movement of eyes
Micturition Inhibitory Area
voluntary control of peeing
Internal capsule: Anterior limb
tracts to frontal lobe and prefrontal cortex
Internal Capsule: Posterior Limb
Corticospinal: initiate voluntary movement
Corticobulbar: to cranial nerves
Primary Somatosensory Cortex
Post Central gyrus
Primary Auditory
Lateral fissure/superior temporal gyrus
Vestibular cortex
posterior to primary somatosensory
Primary visual cortex
calcarine sulcus
Primary motor cortex
precentral gyrus
Supplementary motor cortex
anterior to lower body region of primary motor cortex.
Initiation of movement, planning bimanual and sequential movement
Premotor cortex
anterior to upper body region of primary motor cortex
Planning movements of the mouth
