Serves as a comparison for the evaluating the effect of the treatment
Term
Biological psychology
Definition
branch of psychology concerned with the links between biology and behavior
Term
Neuron
Definition
A nerve cell
the basic building block of the nervous system
Term
Dendrite
Definition
the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
Term
Axon
Definition
the extension of a neuron, ending in branching terminal fibers, through which messages are sent to other neurons or to muscles or glands
Term
Myelin Sheath
Definition
a layer of fatty cells segmentallyencasing the fibers of many neurons
enables greater transmission speed of neutral impulses
Term
Action Potential
Definition
A neural impulse. A brief electrical charge that travels down an axon and is generated by the movement of positively charged atoms in and out of channels in the axon's membrane
Term
Threshold
Definition
Each neuron receives exitatory and inhibitory signals from many neurons. When the excitatory signals minus the inhibitory signals exceed a minmum intensity (threshold) the neuron fires an action potential
Term
Synapse
Definition
a junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
Term
Synaptic gap or cleft
Definition
The tiny gap
Term
Neurotansmitters
Definition
they are released from the sending neuron and travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing it to generate an action potential
