How We Decide: The Neuronal Reward Signal
Using electrophysiologic measures of neuronal activity, we tested theories of reward and decision-making and have found neuronal mechanisms in circuits including dopamine neurons, the striatum, the frontal cortex, and the amygdala that reflect reward and decisions.

Blakemore Chair of Psychiatry, professor of psychiatry and pharmacology Vanderbilt University Medical Center View article as PDF In 1972 the distinguished neurologist Fred Plum famously labeled efforts to reveal structural changes in the brain in schizophrenia the “graveyard of neuropathologists.” This conclusion came on the heels of research dating […]
A Bayesian Approach to the Brain
Florent Meyniel, Ph.D. Cognitive Neuroimaging Unit, Neurospin, CEA, University Paris-Saclay, France View Article as PDF Bayesian concepts are appealing to many researchers in fundamental and applied research, including neuroscience. Bayesian tools, part of probability theory, are useful whenever quantitative analysis is needed, such as in statistics, data mining, or forecasting. However, Bayesian concepts have much […]
Disorders of Consciousness: Brain Death, Coma, and the Vegetative and Minimally Conscious StatesReport on Progress
The authors present two scenarios on what are the disorders of consciousness: wakefulness, awareness, consciousness, coma, vegetative state, minimally conscious state, and brain death.
Why Studies of Fighting Fruit Flies Are Relevant to Understanding Human AggressionReport on Progress
It may surprise some people to learn that fruit flies fight. But male Drosophila melanogaster (more accurately called “vinegar flies”) do fight–to gain access to resources such as food or females.
