A single neuron can represent a disjunction of conjunctions of attributes if the assumption that neurons are single-threshold devices is discarded. Instead, one must assume that such concept neurons are composed of hundreds or thousands of (high-threshold) receptive areas, each containing tens or ...
When you’re learning, important changes happen in your brain, including the creation of new connections between your neurons. 2 The more you practice, the stronger these connections become. As your connections strengthen, the messages are delivered increasingly faster, making them more effective. ...
Bacterial products can act on neurons to alter signaling and function. In the present study, we found that dorsal root ganglion (DRG) sensory neurons are enriched for ANTXR2, the high-affinity receptor for anthrax toxins. Anthrax toxins are composed of p
To differentiate the hESC-derived cortical NE into dorsomedial tissues, we examined the effects of two factors, Wnt and BMP, both of which are known to promote dorsalization of neural tissues2,11,14. Wnts (Wnt 2b, 3a and 5a) are mainly expressed in cortical hem5, and BMPs are apparent...
The wall of the pipe is composed of smaller strands that are braided like rope around the hollow core. Each of the smaller strands consists of the protein tubulin. A single tubulin molecule is small and globular; the strand consists of tubulins stuck together like pearls on a string. The ...
The fitness metrics we used to evaluate model instances are composed of two sets: output attributes that directly affect the muscles which the motor neurons innervate and attributes which capture other key identify- ing attributes of leech heart motor neurons. The former are the relative phase, as...
Intracellular recordings from identified nigral dopamine neurons in the rat revealed that their potentials are composed of four components: (1) a slow depo... AA Grace,BS Bunney - 《Neuroscience》 被引量: 1690发表: 1983年 Dopamine-dependent neurotoxicity of α-synuclein: A mechanism for selective...

aIt is composed of a large number of highly interconnected processing elements (neurons) working in unison to solve specific problems. Neural networks, with their remarkable ability to derive meaning from complicated or imprecise data, can be used to extract patterns and detect trends that are too...
4h). Within such an assembly neuronal somata, glia-like sheaths are much less clear and, if present, are composed of one single layer (Figs. 3a, b, e, 4e, h). The clearly separated packages of somata seem to be aligned in a serially repeated pattern, but this issue needs further ...
