The shape of handwritten characters
TLDR
We address the general problem of defining the shape of a 2D line diagram, with character as a significant special case. Expand

What do the basal ganglia do? A modeling perspective
TLDR
Basal ganglia (BG) constitute a network of seven deep brain nuclei involved in a variety of crucial brain functions including: action selection, action gating, reward based learning, motor preparation, timing, etc. Expand

Informational dynamics of vasomotion in microvascular networks: a review
Vasomotion refers to spontaneous oscillation of small vessels observed in many microvascular beds. It is an intrinsic phenomenon unrelated to cardiac rhythm or neural and hormonal regulation.Expand

An oscillatory neuromotor model of handwriting generation
TLDR
A neuromotor model of handwritten stroke generation, in which stroke velocities are expressed as a Fourier-style decomposition of oscillatory neural activities, is presented. Expand

On the neural substrates for exploratory dynamics in basal ganglia: A model
TLDR
We present a neural network model of basal ganglia that departs from the classical Go/NoGo picture of the function of its key pathways-the direct pathway (DP) and the indirect pathway (IP) and propose a third Explore regime, which denotes random exploration of the space of actions. Expand

A Computational Model of Neuro-Glio-Vascular Loop Interactions
We present a computational, biophysical model of neuron-astrocyte-vessel interaction. Unlike other cells, neurons convey “hunger” signals to the vascular network via an intervening layer of glialExpand

A network model of basal ganglia for understanding the roles of dopamine and serotonin in reward-punishment-risk based decision making
TLDR
We propose a reinforcement learning (RL)-based model of the BG that simulates the interactions between dopamine (DA) and serotonin (5HT) in a diverse set of experimental studies including reward, punishment and risk based decision making. Expand

An efficient multiclassifier system based on convolutional neural network for offline handwritten Telugu character recognition
TLDR
We combine the strengths of four different pattern analysis techniques to develop a powerful and efficient system for handwritten character recognition. Expand

Exploring the cognitive and motor functions of the basal ganglia: an integrative review of computational cognitive neuroscience models
TLDR
This review article focuses on CCN models of the basal ganglia and how they use the neuroanatomy of the BG to account for cognitive and motor functions such as categorization, instrumental conditioning, probabilistic learning. Expand
