Medical Xpress: Researchers discover synaptic logic for connections between two brain hemispheres

Researchers at the Max Planck Florida Institute for Neuroscience have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are arranged within a neuron’s dendritic field. Each of the 20 billion neurons in the cerebral cortex receives thousands […]

Science Daily: Brain cells that make pain unpleasant

If you step on a tack, neurons in your brain will register two things: that there’s a piercing physical sensation in your foot, and that it’s not pleasant. Now, a team of scientists has identified a bundle of brain cells in mice responsible for the latter — that is, the negative emotions of pain. (January […]

News-Medical: Alpha neurofeedback training could be a means of enhancing learning success

Thanks to an interplay of inhibition and disinhibition of certain areas, our brain can always guarantee the processing of particularly important stimuli. Neuronal alpha-oscillations regulate the flow of information in certain regions of the brain so that capacities for the processing of new stimuli are released.

Futurism: The human brain reconstructs memories in reverse order

Neurologically, our brains process the things we see by starting with the small and moving on to the big. If we see a dog, for example, we first notice the visual details (the brown fur and the wagging tail) and then put that information into some sort of context (we decide we’re looking at a […]

Medical News Today: How do our brains remember?

The way in which our brains retrieve memories is still quite poorly understood, and we often remember moments and events in a general fashion, without recalling exact details. Why is that?” We know that our memories are not exact replicas of the things we originally experienced,” says Juan Linde-Domingo, a researcher from the School of […]

Medical News Today: Safer sleeping pills keep brain alert to danger

Most sleeping pills are so strong that the sound of a fire alarm is unlikely to wake those who take them. However, a new study, published in the journal Frontiers in Behavioral Neuroscience, proposes a safer alternative to these drugs. One-third of adults in the United States do not get enough sleep on a regular […]

Quanta Magazine: The brain maps out ideas and memories like spaces

We humans have always experienced an odd — and oddly deep — connection between the mental worlds and physical worlds we inhabit, especially when it comes to memory. We’re good at remembering landmarks and settings, and if we give our memories a location for context, hanging on to them becomes easier. To remember long speeches, […]

Medical Xpress: Researchers track the birth of memories

How and when the ability to form and store memories arises are topics of great interest to neuroscientists. Now Yale researchers have identified three distinct stages in brain development that occur before episodic memories can form.Yale scientists measured brain activity in the hippocampus of newborn rats and found at the beginning of third week of […]
