Neurons
Information is being transmitted throughout our nervous system by neurons.
- electrical impulses are released when they communicate
- action potential is sent
Neurotransmitters
Chemicals that transmit information from one neuron to another
- also transmit info to cells
- includes: muscles, organs, glands
Excitatory neurotransmitters
increase the likelihood that post-synaptic neuron will fire an action potential or neural impulse. and having an excitatory effect.
Glutamate
WHAT: Excitatory neurotransmitter
ROLE: activate/stimulate post-synaptic neuron activity
- learning and memory, neuroplasticity
RELEASED: when a neural pathway with an experience is activated or stimulated
inhibitory neurotransmitters
decrease the likelihood of a post-synaptic neuron firing action potential or neural impulse having an inhibitory effect on the post-synaptic neuron
GABA
WHAT: inhibitory neurotransmitter
ROLE: supress/slow down post-synaptic neuron activity
- anxiety, phobias, mental disorders, Parkinson's disease
