where is a positive diagonal matrix, and is an constant matrix which represents the delayed neuron interconnection.
where is the vector of neuron states at time ; is an matrix representing the neuron inhibition; is an neuron interconnection matrix;,, represents the neuron input-output activation and is the continuous -periodic vector function denoting neuron inputs.
where x = ( x 1, x 2, …, x N ) T ∈ R N is the vector of neuron state, A = diag ( a 1, a 2, …, a N ) is an N × N diagonal matrix, where a i < 0, i = 1, 2, …, N, are the neuron self-inhibitions; B = ( b i j ) is an N × N positive definite matrix, which represents the neuron interconnection matrix.
In the adult, the neural retina consists of approximately 55 distinct cell types histologically structured into three layers of cells (photoreceptors, intermediate neurons and ganglion cells) and two layers of neuronal interconnections (outer and inner plexiform layers) [ 3].
Scientists theorize that this excess of working neurons and interconnections compensates for damaged ones to ward off dementia.
This approach would involve creating a very detailed 3-D map of an actual brain showing neurons, synaptic interconnections and other relevant detail by scanning slices of it and generating an image using computer software.
The ICNS contains afferent neurons [ 26, 27], sympathetic efferent postganglionic neurons [ 28– 30], parasympathetic efferent postganglionic neurons [ 31], and a large population of local circuitry neurons that perform interconnections within the intrinsic cardiac ganglionated plexuses [ 28, 32].
The plexiform layers are regions in which the neurons make their interconnections.
He had been thinking about one of the most vexing problems in neuroscience: how to create a detailed image of all the brain's neurons and their interconnections.
