ethereal entity—would seem to force us to conclude that our thoughts and actions, which are all the product of physical neuronal processes, must be entirely dependent on preceding causes—just like everything else in the universe.3
Deep learning architectures have many variants and some have recurrent connections in addition to feedforward connections, yet they predominantly share the structure of a deep hierarchy. The layered, hierarchical structure that today’s deep learning architectures commonly adopt was inspired by earlier ...
Seeing the Brain in Action: How Multiphoton Imaging Has Advanced Our Understanding of Neuronal Functiondoi:10.1017/S143192760808080XGrace Stutzmann
To gain an intuitive understanding of the data, visualizeneuronal activity, and form hypotheses, the team successfully reduced the number of dimensions in the data, in some ways like converting a three-dimensional image into a flat one, and without losing the data’s integrity. ...
The research focuses on engrams, which are neuronal cells in the brain that store memory information. “Engrams are the neurons that are reactivated to support memory recall,” says Dheeraj S. Roy, PhD, one of the paper’s senior authors and an assistant professor in the Department of Ph...
To study neuronal processing in silico we created BNMs for the 650 subjects using a tuning algorithm that fits each participant’s simulated FC with their empirical FC (Figs. 2 and 3). The BNMs use coupled neural mass models to simulate the electric, synaptic, firing, and hemodynamic (fMRI...
The Reticular Activating System, with its locus in the thalamus and hypothalamus, is a vast network of neuronal afferent and efferent connections to the entire brain and body. Thus it is the perfect candidate for the brain’s Command and Control System―the de facto manager and coordinator of ...
Chanda said that several mutations in the Gephyrin protein have been associated with neurological disorders like epilepsy, which alters neuronal excitability in the human brain. That makes understanding its basic cellular function an important first step towards treatment and prevention. "Now that we bet...
coincide in the hippocampus, the brain's 'memoryhub.' This was a good indication that the synchronization of these sleep rhythms may be involved in memory consolidation. What was missing, however, was evidence that they in fact impact neuronal firing rates, i.e., the 'hard currency' of lea...
"As the animal is expressing one choice, the wiring of the neuronal circuit may help stabilize that choice by suppressing other choices," Lee said. "This could be a mechanism that helps an animal maintain a decision and prevents 'changes of mind.'" The findings need to be confirmed in hum...
