PSYC 2110 Chapter Notes - Chapter 6 part 1: Thalamus, Neuroglia, Motor Control
Document Summary
When signals are sent along neurons, an electrical field is generated that can be measured: to measure electrical activity: electrodes placed on particular point of scalp. Electrodes detect change in electrical voltage as a result of neural activity: this technique generates maps of neural activity on the surface of the brain. Greater number of electrodes = greater precision and accuracy. Infants must be sleeping in order to obtain scans because minimal movement is required: diffusion tensor imaging (dti) , an imaging technique that measures the diffusion or movement of water molecules through neural tracts that connect brain structures. Capable of providing information about how the different structures of the brain are connected. Has been used to investigate that development of white matter and the neural tracts connecting brain structure. White matter decreases with age, likely reflecting the developmental maturation of axons and their myelination.
