Simple Math Predicts Electrical Activity in The Brain, Study Shows

Posted by in categories: mathematics, neuroscience

Through a vast network of nerve fibers, electrical signals are constantly traveling across the brain. This complicated activity is what ultimately gives rise to our thoughts, emotions, and behaviors – but also possibly to mental health and neurological problems when things go wrong.

Brain stimulation is an emerging treatment for such disorders. Stimulating a region of your brain with electrical or magnetic pulses will trigger a cascade of signals through your network of nerve connections.

However, at the moment, scientists are not quite sure how these cascades travel to impact the activity of your brain as a whole – an important missing piece that limits the benefits of brain stimulation therapies.

An Introduction to Neuroinformatics

Posted by in categories: biotech/medical, neuroscience

Details

The goal of brain imaging is to provide in-vivo measures of the human brain to better understand how the brain is structured, connected and functions.
In this talk, we will discuss how to analyze brain imaging data in order to make sense of the large amount of data that comes out of the scanner.

The First-Ever Complete Map of an Insect Brain Is Truly Mesmerizing

Posted by in categories: mapping, neuroscience

After 12 years of work, a huge team of researchers from the UK, US, and Germany have completed the largest and most complex brain map to date, describing every neural connection in the brain of a larval fruit fly.

Though nowhere near the size and complexity of a human brain, it still covers a respectable 548,000 connections between a total of 3,016 neurons.

Decoding the Brain

Posted by in categories: nanotechnology, neuroscience, physics

How does the brain retrieve memories, articulate words, and focus attention? Recent advances have provided a newfound ability to decipher, sharpen, and adjust electrical signals relevant to speech, attention, memory and emotion. Join Brian Greene and leading neuroscientists György Buzsáki, Edward Chang, Michael Halassa, Michael Kahana and Helen Mayberg for a thrilling exploration of how we’re learning to read and manipulate the mind.

The Kavli Prize recognizes scientists for their seminal advances in astrophysics, nanoscience, and neuroscience — topics covered in the series “The Big, the Small, and the Complex.” This series is sponsored by The Kavli Foundation and The Norwegian Academy of Science and Letters.

Scientists create first detailed map of insect brain with 3,016 neurons

Posted by in categories: chemistry, neuroscience

Perhaps, human consciousness can be fully understood one day.

Researchers from Johns Hopkins and Cambridge universities have created the first-ever map of the wiring patterns of every neuron in the fruit fly larval brain.

Neurons in an organism’s nervous system, including the brain, are linked to one another by synapses.

Scientists identify pattern of brain activation that differentiates drug users from non-users

Posted by in categories: biotech/medical, neuroscience

A series of three neuroimaging studies identified a pattern of neural activation involving specific brain regions that differentiates drug users from non-users with 82% accuracy. Researchers named the pattern the Neurobiological Craving Signature (NCS). Their findings have been published in Nature Neuroscience.

Craving is a strong desire to use drugs or eat. It has long been considered a key factor driving substance abuse and overeating. It is one of the criteria used for diagnosing substance use disorders. Craving is often induced by exposure to certain stimuli. In the case of overeating, these include the smell or sight of food. In the case of drugs, craving can be induced by one being in places or situations he/she associates with taking drugs or being offered drugs. This is called cue-induced craving.

Earlier studies of craving have successfully relied on self-reported craving, but recent research has focused on discovering its biological basis. Human neuroimaging studies have identified neural circuits related to the risk of substance abuse. Some brain circuits have been found to be involved in different substance use disorders and risky behaviors. These include specific parts of the ventromedial prefrontal cortex (vmPFC), ventral striatal/nucleus accumbens (VS/NAc) and insula regions of the brain. These regions also appear to play a role in weight gain and obesity.
