Major inhibitory transmitter in brain (IPSP).
Located everywhere, most common Keeps brain cells quiet, under control, at rest Boost: sedation, alcohol |
GABA:
Where is it located What does it do Effects when boosted and blocked |
|
|
major excitatory neurotransmitter (EPSP)
Located everywhere Associated with learning Too much: seizures, too little: Schizophrenia (not able to connect things) |
Glutamate:
Where is it located What does it do Effects when boosted and blocked |
|
|
Initiation of voluntary motor sequences and motivation
Located in the midbrain and sent to dorsal and ventral straitum Boost: attention alertness Lack: Parkinson's, treatment for schizophrenia |
Dopamine:
Where is it located Effects when boosted and blocked |
|
|
Behavioral inhibition, control impulses
Located in midbrain and goes to everywhere (frontal cortex) Boost: antidepressant, treatment for other disorders, hallucinogen Lack: Migraine, depression, overeating |
Serotonin:
Where is it located Effects when boosted and blocked |
|
|
Selective attention, signal to noise ratio
Fight or flight response Located in the midbrain (locus coereleus) and sent to everywhere Boost: Early antidepressant, Lack: stage fright, treats hypertension |
Norepinephrine:
Where is it located Effects when boosted and blocked |
|
|
Cognition and memory
Located everywhere (basal nucleus --> cortex; septum--> hippocampus) Boost: treatment for Alzheimer's |

|
Forebrain, Midbrain, Hindbrain
|
Brain Subdivisions
|
|
|
Cerebrum: complex sensory, motor, and decisions functions (telencephlon)
Hypothalamus: brain control over hormones, controls body Thalamus: Sends sensory information to cortex |
Forebrain
|
|
|
Pons: Fine tunes motor messages
Medulla: Automatic functions (breathing) |
Hindbrain
|
|
|
Occipital: visual processing
Parietal: Complex sensory processing Frontal: Motor strip, decision making Temporal: auditory, fear/emotion (amygdala), memory consolidation (hippocampus) |
