Molecular link between chronic pain and depression revealed
Inhibitory inputs to the neural circuit between the dorsolateral bed nucleus of the stria terminalis (dlBNST) to the ventral tegmental area (VTA) increase when a person is in chronic pain. This alteration is mediated by enhanced corticotropin-releasing factor signaling within the dlBNST, leading to suppression of the mesolimbic dopaminergic system. The result is depressive mood and anhedonia associated with chronic pain.... Read More...
New method classifies brain cells based on electrical signals
Researchers distinguish between four distinct classes of neurons based on their spiking information.... Read More...
How the brain finds order amidst chaos
Amidst noise and chaos, cortical neurons work in a team to communicate and allow the brain to find order.... Read More...
The way a single neuron processes information is never the same
When a neuron receives information, dendrites functionally work together to adjust for the complexity of the input.... Read More...
The fractal brain, from a single neuron’s perspective
Researchers say measuring signals from a single neuron may be as good as capturing information from many neurons at once.... Read More...
Neurons’ “antennae” are unexpectedly active in neural computation
When the soma of specific neurons is active, the dendrites of the same neuron are also active, even when animals are not engaged in a cognitively demanding task. ... Read More...
New microscopy technique peers deep into the brain
A new microscopy technique integrates existing and novel approaches to build a clearer picture of the workings of neurons in the brain. The technique captures cellular activity across large tissue volumes in greater detail than previous techniques have allowed for.... Read More...
New pattern of brain ageing identified
New patterns of brain ageing across the human lifespan have been revealed by researchers analysing microstructural changes in the brain’s white matter. ... Read More...
Quick thinking? It’s all down to timing
A pairing of presynaptic and postsynaptic activity in a population of hippocampal neurons can reduce the required number of synaptic plasticity evoking events. When spikes occur within ten milliseconds of each other, synapses strengthen for up to four hours.... Read More...
