Researchers discover novel compound that helps curtail progression of temporal lobe epilepsy

Researchers at the LSU Health New Orleans Neuroscience Center of Excellence have found that a novel compound they discovered helps curtail the onset and progression of temporal lobe epilepsy.

Improving prefrontal cortex activity could help autistic people regulate emotions

Tantrums, irritability, self-injury, depression, anxiety. These symptoms are associated with autism, but they're not considered core symptoms of the disorder. Researchers from the UNC School of Medicine are challenging this assertion. They have used functional MRI to show that - when it comes to the ability to regulate emotions - brain activity in autistic people is significantly different than brain activity in people without autism.

Cellular mechanisms of alcohol dependence: an interview with Dr Sanna, TSRI

In the brain there are both excitatory and inhibitory neurotransmitters. These are molecules that are released from nerve endings in the brain and in the periphery and either excite or inhibit other nerve cells, also known as neurons.

Psilocybin in magic mushroom inhibits negative emotions in brain, shows study

Emotions like fear, anger, sadness, and joy enable people to adjust to their environment and react flexibly to stress and strain and are vital for cognitive processes, physiological reactions, and social behaviour.

Brain disconnect leaves teen brain less able to judge trustworthiness

Making a snap decision usually means following your initial reaction -- going with your gut. That intuitive feeling sprouts from the limbic system, the evolutionarily older and simpler part of the brain that affects emotion, behavior and motivation.

Researchers investigate sex differences in brain structure

Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews.

Findings suggest possible clinical uses of ecstasy in treating anxiety and PTSD

Brain imaging experiments have revealed for the first time how ecstasy produces feelings of euphoria in users.

Severely neglected children more prone to indiscriminate friendliness

Children who experience profound neglect have been found to be more prone to a behavior known as "indiscriminate friendliness," characterized by an inappropriate willingness to approach adults, including strangers.

Regular cannabis users have increased levels of impulsive behaviour, reveals research

New cocaine and cannabis research reveals that regular cannabis users have increased levels of impulsive behaviour. It had previously been argued that this increased impulsivity after cannabis administration was only experienced by occasional users, but that regular users were no longer affected in this way.

Multimodal neuroimaging approach helps study structural and functional abnormalities in brain

Major depressive disorder is associated with a dysregulation of brain regions including the prefrontal cortex and limbic system. The relationship between structural and functional abnormalities in these brain regions in depressed patients is far from clear. However, both types of changes are assumed to underlie the symptoms of this disorder.

Physicians stimulate patients' medial forebrain bundles to reduce major depression

Researchers from the Bonn University Hospital implanted pacemaker electrodes into the medial forebrain bundle in the brains of patients suffering from major depression with amazing results: In six out of seven patients, symptoms improved both considerably and rapidly.

Researchers analyze Brazilian mediums' cerebral blood flow during practice of psychography

Researchers at Thomas Jefferson University and the University of Sao Paulo in Brazil analyzed the cerebral blood flow (CBF) of Brazilian mediums during the practice of psychography, described as a form of writing whereby a deceased person or spirit is believed to write through the medium's hand.

Balance abnormalities can exacerbate asthma symptoms

Asthma patients could be at a higher risk of worsening symptoms due to problems with their balance, according to new research.

Important insight into association between childhood maltreatment and suicide

Exposure to childhood maltreatment increases the risk for most psychiatric disorders as well as many negative consequences of these conditions. This new study, by Dr. Gustavo Turecki and colleagues at McGill University, Canada, provides important insight into one of the most extreme outcomes, suicide.

Scientists image process of consciousness after general anesthesia

Awakening from anesthesia is often associated with an initial phase of delirious struggle before the full restoration of awareness and orientation to one's surroundings. Scientists now know why this may occur: primitive consciousness emerges first. Using brain imaging techniques in healthy volunteers, a team of scientists led by Adjunct Professor Harry Scheinin, M.D. from the University of Turku, Turku, Finland in collaboration with investigators from the University of California, Irvine, USA, have now imaged the process of returning consciousness after general anesthesia.

Researchers analyze link between maternal-child relationship and adolescent obesity

The quality of the emotional relationship between a mother and her young child could affect the potential for that child to be obese during adolescence, a new study suggests.

Modern humans have a better sense of smell than Neanderthals

Compared to Neanderthals, modern humans have a better sense of smell. Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain organization.

Intensive maternal care during infancy promotes effect of NPY in brain

Neuropeptide Y (NPY) is the most abundant peptide hormone of the central nervous system. It is involved in various processes including stress management, the development of anxiety behaviour and body weight regulation. A collaborative research group including scientists from the Max Planck Institute for Medical Research in Heidelberg has demonstrated using mice that intensive maternal care during infancy promotes the effect of NPY in the brain.

Targeted brain stimulation increases cigarette cravings

Targeted brain stimulation increases cigarette cravings, a new study in Biological Psychiatry has found, which may ultimately lead to new treatments that reverse these effects. Cues associated with cigarette smoking, such as watching someone else smoke, elicit craving and may provoke relapse when smokers are attempting to quit.

Researchers reveal how motivation facilitates motor functional recovery in stroke, SCI patients

An effective recovery has been observed in stroke patients and those with spinal cord injuries who have strong vitality and motivation to rehabilitate in clinical practice. However, it was not really clear how motivation facilitates functional recovery in brain science.
