Limbic

this means border

Limbic System

structures on the margins of cerebral cortex

Limbic System

system that regulates motivated behavior (e.g. fleeing, feeding, fighting, and sexual behavior)

Hippocampus

Limbic System: "seahorse" in greek

Hippocampus

Limbic System: learning and memory

Hippocampus

Limbic System: damage causes anterograde amnesia

anterograde amnesia

difficulty to form new long-term declarative memory (facts, language, personal experience)

Amygdala

Limbic System: Almond-shaped

Amygdala

Limbic System: fear, rage, aggression, interacts with hippocampus during encoding and storage of emotional memories

Amygdala

near the bottom of the limbic system

Amygdala

Limbic System: damage causes inability to respond appropriately to dangerous situations

Cingulate Cortex

Limbic System: fold of cortical tissue on surface of cerebral hemisphere

Anterior Cingulate Cortex (ACC) & Posterior Cingulate Cortex (PCC)

Cingulate Cortex < (2)

Anterior Cingulate Cortex (ACC)

Limbic System < Cingulate Cortex: decision making, error, detection, anticipation of reward, empathy, processing of pain (phys and social)

Anterior Cingulate Cortex (ACC)

Limbic System < Cingulate Cortex: some influence on autonomic functions

Posterior Cingulate Cortex (PCC)

Limbic System < Cingulate Cortex: Eye movement, spatial orientation, and memory

Septal Area

Limbic System: electrical stimulation results is pleasurable while lesion results to uncontrollable rage and attack behavior

Olfactory Bulbs

Limbic System: Receive and process information about smell

Mamillary Bodies

Limbic System: sense of direction and memory

Fornix

Limbic System: Fiber pathway connecting mammillary and hippocampus, functions in memory

Basal Ganglia

Group of subcortical structures lateral to the thalamus

Basal Ganglia

voluntary motor control

Basal Ganglia

damage implicated in parkinson's disease, huntington's disease, ADHD, and OCD

caudate nucleus, putamen, globus pallidus, nucleus accumbens

Basal Ganglia's important structures < (4,)

nucleus accumbens

Basal Ganglia: role in experience of reward

Limbic System

forms a fringe along the inner edge of the cerebrum
