Photoreceptorssual pathway. Recent reports dealing with vertebrate photoreceptors agree in the somewhat startling disclosure that darkness is the positive stimulus, whereas light inhibits the excitatory state of the receptors. This is no more the case with the neurons further down the line of information transmishematuria 发表于 2025-3-28 20:10:49
Approaches to Brain Functiont this chapter and after a glance at Figure 35 should proceed to Chapter 11. Those who really want to know are advised to consult a text on the history of psychology or of neurophysiology, for in this space the topic can hardly be done justice.哀求 发表于 2025-3-29 01:53:59

Central Coding in the Somatic Sensesture supporting each of the following entirely factual statements: the dorsal columns of the spinal cord transmit information concerned with fine discrimination of mechanical stimuli; damage to these columns does not degrade performance based on such discriminations; all the input from spinal cord t核心 发表于 2025-3-29 10:12:50
The Central Code of Hearing precise. Moreover the ‘volleying’ of neurons in third- and higher-order neurons in the auditory nuclei of the brain stem, seems to be optimal during relaxed inattentiveness of the subject and to become less strict when the animal is alerted to the sound stimulus.

The Central Code of Sightneurons of the visual pathway have receptive fields organized into excitatory and inhibitory zones. Between lateral geniculates and the cortex two changes take place: one is the predominance of binocular convergence in the cortex, and the other is the change of the shape of the optimal stimulus fromchemical-peel 发表于 2025-3-29 16:15:08
The Central Code of the Chemical Sensesd cortical representation of taste is as yet ., but is currently being surveyed..Two theories of the representation of odor quality are discussed: one is based on topographic representation of smells, the other on a frequency-code.Processes 发表于 2025-3-29 21:04:38
