Document Summary

Researchers are biological psychologists or neuroscientists they study the relationship between the brain and the psyche (mind). Neurons are brain cells, specialized in communications with each other. Approximately 100 billion neurons with 160 trillion connections between them. Cell body (soma) centre of the neuron; builds new cell components. Dendrites branch like extensions that receives information from other neurons, comes into brain. Axons (cid:862)tails(cid:863) of the (cid:374)euro(cid:374) that spread out fro(cid:373) the (cid:272)ell (cid:271)ody a(cid:374)d tra(cid:374)s(cid:373)it i(cid:374)fo, (cid:373)o(cid:448)es a(cid:449)ay fro(cid:373) brain. Axon terminal knob at the end of the axon containing synaptic vesicles filled with neurotransmitters. Neurotransmitters (nts) chemical messengers that all neuron to neuron communication. Synapse space between neurons through which nts travel. Neurons respond to nts by generating electrical activity. Recordings made of the electrical activity inside and outside neurons. Resting potential: when there are no nts acting on a neuron (-60 millivolts). More negative particles inside than outside the neurons.
