Document Summary

Biological psychology: the study of the connection between biology and behavior, the nervous system is living tissue composed of cells, neurons, fundamental blocks of communication, glia, cells that support and nourish the neurons, 50% of our brain volume. Why are neurons important: motor (efferent) neurons, sensory (afferent) neurons, mirror neurons, mirror other people"s a(cid:272)tio(cid:374)s or feeli(cid:374)gs, a mechanism for feeling empathy. Structure/function of a neuron: receive info by the dendrites, integrate info in the soma, transmit info in the axon, myelin sheath speeds up the transmission, what disease results when myelin layer is destroyed, ms, terminal buttons, synapse. Presynaptic sending out a signal to the postsynaptic neuron. Communications between neurons: neurotransmitters chemicals that transmit info from one neuron to another, nt"s are fu(cid:374)da(cid:373)e(cid:374)tal to the (cid:271)rai(cid:374) Frontal lobe: reasoning, planning, problem solving, speech, motor control, sense of smell. Bro(cid:272)a"s area: speech production, located in left frontal lobe. Bro(cid:272)a"s asphia: can understand language, ca(cid:374)"t speak.
