Cognitive Psychology connecting mind, research, and everyday experience Ch:2 axon, but they have specialized receptors that pick up information from the environment action potential - Ans - * as the impulse passes the recording electrode, the charge rises to +40mV compared to the outside *lasts 1 millisecond (1/1000second) Axons - Ans - (also called Nerve Fibers) * are usually long processes that transmit signals to other neurons Cajal (conclusions about the neuron) - Ans - * has a receiving and transmitting end- (transmit signals) (1)there is a small gap between the end of the axon and the dendrites of the cell body (gap=synapse) (2)neurons are not connected indiscriminately to other neurons, but form connections only to specific neurons -this form a group of interconnected neurons, together form the (Neural Circuit) (3)there are also neurons that are specialized to pick up information from the environment, such as the neurons in the eye, ear, and skin (called receptors) - receptors are similar to brain neurons in that they have an axon, but they have specialized receptors that pick up information from the environment **"the person who made this cellular study of mental life possible"** Cell body - Ans - *is the metabolic center of the neuron *it contains the mechanisms to keep the cell alive Charles Gross - Ans - (how are complex stimuli represented by the firing of the neurons in the BRAIN?) *recorded from single neurons in the monkey's temporal lobe * required a great deal of endurance by the researchers because the experiment typically lasted 3-4 days ****the discovery that neurons in the temporal lobe respond to complex stimuli came a few days into the experiment when they found a neuron that refused to respond to any of the standard stimuli like oriented lines or circles or squares (a shadow ) Cognitive Neuroscience - Ans - *the study of the psychological basis of cognition Dendrites - Ans - *branch out from the cell body is to receive signals from other neurons
