metabolic center of the neuron
cell body
to receive signals from other neurons
dendrites
transmit signals to other neurons
axons (nerve fibers)
a small gap between the end of a neuron’s axon and the dendrites or cell body of another neuron.
synapse
forms groups of interconnected neurons together
neural circuits
he was able to record electrical signals from single sensory neurons, which he was awarded the Nobel Prize in 1932.
Edgar Adrian

microelectrodes
when the signals reach the synapse at the end of the axon, what chemical is released?
neurotransmitter
chemical messengers, carries chemical signals from one neuron to the next target cell.
neurotransmitters
fight or flight neurotransmitter
adrenaline
calming neurotransmitter
gaba
concentration neurotransmitter
noradrenaline
learning neurotransmitter
acetycholine
pleasure neurotransmitter
dopamine
memory neurotransmitter
glutamate
mood neurotransmitter
serotonin
euphoria neurotransmitter
endorphins
experiences is based on representations in the person’s nervous system.
principle of neural representation
they respond to specific stimulus features such as orientation, movement, and length.
feature detectors neurons
the structure of the brain is changed by experience.
experience-dependent plasticity
the idea that the brain operated as an indivisible whole as opposed to specialized areas.
cortical equipotentiality
In 1861, he published his study of patients who had suffered brain damage due to strokes that caused disruption of the blood supply to the brain
Paul Broca
strokes that caused damage to an area in the frontal lobe is called what?
Broca’s area
slow, labored, ungrammatical speech caused by damage to Broca’s area
Broca’s Aphasia
