Acute stroke in 3 brain territories suggests cancer

Over the past several decades cancer has increased to rival heart disease as the leading cause of death in the United States. Non-infectious endocarditis and cancer-associated hypercoagulation (C-AH) have both been suggested as a source of stroke

The risks of brain damage after hyperthermia

This article describes the unintended neurological consequences after a period of fever or hyperthermia. A fever may have many causes, including after strenuous exercise, being in a heatwave, taking certain drugs and medications, and various illnesses. Hyperthermia

Do we hallucinate when we sleep?

By definition, hallucinations occur only when we are fully awake state. Yet the similarities to experiences that occur during the transition between sleep and wakefulness; dreams; and incubus phenomena have been known for a long time. In

How sugar and fat affect our brain leading to a high blood pressure?

Obesity is a serious, chronic and pandemic disease that can have a negative effect on many systems in our body. People who are overweight or obese have a much greater risk of developing serious diseases including hypertension.

Reading “don’t cut the bread” triggers motor inhibition in the brain

All languages have negation markers, which allow the speakers to deny something, for instance the presence of an object (there is not bread), a feature (John is not cleaver), an action (you do not play piano), and

Chromosome gains and losses in the human brain are probably less important than previously thought

In general, each human cell contains 46 chromosomes: 23 chromosomes from each parent. Before a cell divides all chromosomes are duplicated. The cell has several mechanisms to ensure that during cell division the chromosomes are evenly distributed

Can prolonged exposure to cortisol excess have an irreversible effect on emotion-related brain areas?

Cortisol is a hormone produced in humans by adrenal glands and it is necessary to live. In healthy people, cortisol level naturally increases in response to stressful situations, but when cortisol level in the body is too

A new representation of the nervous system: the hypermatrix

It is a big challenge to develop the most appropriate mathematical model to describe the electrical activity of different groups of neurons. There are more neurons in the nervous system (about 86 billion) than we have seconds

CSF-1 receptor and its activators – new players in the nervous system and neurological disease

Macrophages, meaning big eater (from the Greek, makros (large) and phagein (to eat)), are cells, present in all tissues of the body, that engulf and degrade large foreign particles, such as microbes and also scavenge abnormal self

Listen up: Our brains prepare to ‘tune in’ to a voice of interest

A fundamental challenge of human communication is to understand what someone’s saying in the presence of background noise—for example, when several conversations occur at the same time. In these situations, accurate speech understanding relies on the critical

Of flies and men: investigating human disease in fruit flies

My lab studies diseases which affect the neurons connecting our brains to the muscles throughout our bodies, called motor neurons. In particular, we are interested in the hereditary spastic paraplegias (or HSPs for short), a group of

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,

Mapping red nucleus connections in humans by using dMRI and tractography

Human brain is an enormous and complex network. Central to current scenario on brain networks is the concept of the connectome, which likely describes patterns at multiple levels of scale, for instance, by encompassing connections between the

Inflammation alters brain function and pain processing centrally

In the last couple of years, some fascinating abilities of the immune system have emerged: The immune system is tightly interconnected with the nervous system, and can directly affect how the brain functions, and how a person

What makes people under stress more vulnerable to become addicted to cocaine? Brain BDNF may be the key

Annually, drug addiction leads to 0.5 – 1.3% of mortality for people between 15-64 years of age and has an estimated economic impact of $524 billion in the U.S, due to addiction-related health care, loss of productivity,

Brain bypass: current trends in the treatment of patients with complex cerebrovascular disease

Cerebral Revascularization or bypass is the neurosurgical equivalent of coronary artery bypass. In these procedures a surgeon uses existing vessels in the head and brain or vessels harvested from another part of the body to either replace
