Document Summary
Psyco 275, textbook summary: chapter 7: how do we study the brain"s structures and functions. Functional near- infrared spectroscopy (fnirs): gathers light transmitted through cortical tissue to image oxygen consumption in the brain. Fnirs allows investigators to measure oxygen consumption as a surrogate marker of neural activity in relatively select cortical regions, even in newborn infants. Neuropsychology is the study of the relations between brain function and behaviour, especially in humans. Speech is located in the third frontal convolution of the left frontal lobe- a region now called broca"s area. Histological tools: brains were sectioned postmortem and the tissue stained with various dyes. Staining sections of the brain tissue can identify cell bodies in the brain viewed with a light microscope, and selectively staining individual neurons reveals their complete structure. The hippocampus is necessary for remembering the context in which we encounter information.
