A method for studying the information processing mechanism of homing pigeon rgc to ot

Abstract

The invention discloses a method for studying the information processing mechanism of pigeon RGC to OT, belonging to the field of biomedicine, comprising step 1: performing sparse noise stimulation and black and white brightness stimulation on the pigeon neuron cluster to obtain ON- OFF neurons; Step 2: Conduct grating stimulation experiments on neurons, and then use information theory to analyze neuron responses; Step 3: Conduct character reconstruction experiments on neurons, and draw definite conclusions; Step 4: Build 4 model frameworks, And obtain the activation curve; Step 5: Obtain the ON filter and OFF filter in the model, verify the four models, and then evaluate the performance of each model in combination with the activation curve, and obtain the first action that the retina can use the neuron cluster Based on the conclusion that the potential (First-Spike) time delay quickly encodes the spatial information, the present invention solves the problem that the existing technology does not study the encoding mechanism of the OT region of birds in place, and the information processing mechanism is not clear.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a method for studying the information processing mechanism from RGC to OT of homing pigeons. Background technique [0002] In the visual system of animals, visual information is often transmitted through neural electrical signals in neural pathways, and among the neural electrical signals, high-frequency spike signals are very important, carrying key information about neuron activity. [0003] Birds have a well-developed visual system. The Optic Tecturn (OT) is a very important nerve nucleus in the process of visual information processing in birds. The main target area has a certain degree of integration of visual information. Studies have shown that OT neurons receive input from RGCs, however, the information processing mechanism of the pathway from RGCs to OT is still unclear. Therefore, the research on the information coding mechanism of the OT area can reveal its information process...
