Cocaine is a strong central nervous system stimulant that increases levels of the neurotransmitter dopamine in brain circuits regulating pleasure and movement. Normally, dopamine is released by neurons in these … Continue Reading Researchers begin to map brain regions and circuits changed by cocaine-use.
The brain controls most of a person’s behaviour and changes in how brain areas work and communicate with each other can alter this behaviour and lead to impairments associated with … Continue Reading New neuroimaging technique shows how the ‘social brain’ is impaired in autism.
Human multitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. Studies have shown that some people can be trained … Continue Reading Neuroimaging study maps the neural basis of multitasking.
When a person walks around the block, their body is mostly on autopilot; they don’t have to consciously think about alternating each step or which muscles it takes to lift … Continue Reading Researchers visualise motor neurons in real-time on a genetic sub-type level.
A new study from researchers at Stanford University found that synchronized physiological interactions between remote regional brain neuron networks have genetic underpinnings. The research was performed at Stanford but was … Continue Reading Researchers begin to map the neurogenetics of neural network theory.
Study begins to map the epigenetics of brain plasticity, the switch which changes neuronal function.
Scientists at the Salk Institute have discovered that the role of neurons, which are responsible for specific tasks in the brain, is much more flexible than previously believed. By studying … Continue Reading Study begins to map the epigenetics of brain plasticity, the switch which changes neuronal function.
Researchers at the Max Planck Institute, VU University Amsterdam and Max Planck Florida Institute state that they have succeeded in reconstructing the neuronal networks that interconnect the elementary units of … Continue Reading New 3d neuronal labeling technique provides most comprehensive study of cortical circuitry to date.
About one in five people experience tinnitus, the perception of a sound, often described as ringing, that isn’t really there. Now, an opensource study in the journal Current Biology, has … Continue Reading Researchers begin to map and record tinnitus in the brain.
A precision genetic analysis has yielded a surprising result, a network of neurons control breathing within the vagus nerve. Among these function-specific network of neurons, two types are dedicated to … Continue Reading Researchers identify neural networks within the vagus nerve responsible for breathing.
The ability to learn associations between events is critical for survival, but it has not been clear how different pieces of information stored in memory may be linked together by … Continue Reading Researchers optogenetically create artificial link between unrelated memories.
