Prefrontal-auditory communication in fear discrimination

Identifying neural networks that infer safety versus danger is of great interest in the scientific field. Fear generalization reduces the chances of an animal’s survival and leads to psychiatric diseases, such as post-traumatic stress disorders and phobias

Consciousness hidden in the brain fissure

Consciousness, informally stated as the subjective feeling of being, comprises of two basic components—arousal (wakefulness) and awareness (awareness of environment and self). Although the posteromedial cortex (PMC), an area hidden in the posterior interhemispheric fissure, has been

Can glucose or fructose consumption impair memory?

Can glucose or fructose consumption impair memory

The intake of simple sugars in the human diet has risen in the last decades, especially due to the elevated consumption of sugar-sweetened beverages. This increase in simple sugar consumption has been associated with metabolic pathologies, such

Ventral medial prefrontal cortex: is it a brain target for drug-seeking control?

A weak direct current applied non-invasively (transcranial Direct Current Stimulation – tDCS) over the scalp in both sides over the frontal lateral region of the head, corresponding to what it is called as the dorsolateral prefrontal cortex,

A systems-level view of cerebellar function: The interplay between cerebellum, basal ganglia, and cortex

The cerebellum is a key brain region involved in many motor functions. It contributes to coordination, precision, and accurate timing of movements as well as to motor learning and adaptation. Alongside its role in motor control, it

The effects of brain stimulation on cognitive inhibition

The term cognitive inhibition refers to the ability to control or suppress irrelevant responses, and to adopt instead relevant and flexible responses. A common situation that requires cognitive inhibition includes for example, the resistant to check messages

The psychopath’s unusual focus on reward

The word “psychopath” conjures up the image of the deranged serial killer. The reality is very different. Psychopathy, especially the primary variant, is a genetically determined disorder that leads to a serious lack of emotional experience, which,

Roots of risky decisions in drug dependence

Decision-making is a key activity of everyday life. Consequently, disturbances in the ability to make appropriate decisions or anticipate their possible consequences can result in massive social, medical, and financial problems. In the Iowa gambling test developed

A novel perspective on schizophrenic-like symptoms

One of the key questions in neuroscience involves understanding how the brain processes cognitive functions – like learning new information, making adaptive decisions, and engaging in social interactions with others. We know that these activities occur across

Epileptic rats as perfect models to understand epilepsy?

Epilepsy is a neurological disease that affects about 1% of the population in the world, most of them being children and teenagers. Animals suffering from epileptic seizures can also be found in several species (dogs, cats, chicken,
