Biopsychology: the study of the biological bases of thoughts, feelings, and behaviours. Neural impulses: the beginning: hodgkin and huxley in the 1950"s were able to study the neurons in giant. Squid without microscopes: they noted a saline solution inside and outside of neurons, this saline solution contained ions, they noticed that neurons were different at rest than when activated. Neurons: specialized cells, brain contains 100 billion neurons at birth. Less able to reproduce than other cells. Easier for young people than old people to reproduce neurons: designed to receive, process, and send messages, resting potential of -70 millivolts. This means that at rest, the neurons have a negative charge inside of them compared to the outside: contains: Contains the biochemical structure needed to keep the neuron. Collect messages from neighbouring neurons and send them to. Can receive input from 1000 or more neighbouring neurons the cell body. Nucleus carries the genetic information that determines how the cell develops and functions.
