Cortex over reflex: Study traces circuits where executive control overcomes instinct

A new study by MIT neuroscientists demonstrates that neurons in the anterior cingulate cortex project connections into an evolutionarily older region called the superior colliculus, overriding its basic commands for reflexive movement. The research shows how inhibitory control from the ACC modulates the SC's response to facilitate exec...

Neuroscientists measure fans' reactions to the big game

A study published in Neuron found that surprise during sports viewing leads to changes in brain patterns, particularly in the prefrontal cortex and pupil dilations. The researchers also discovered a link between dopamine-rich regions and increased activity when subjects' preferred teams scored.

New mechanism of pain control revealed

Researchers at Kyushu University have discovered a unique population of spinal cord astrocytes that produce pain hypersensitivity. Stimulation of noradrenergic neurons activates these astrocytes, leading to enhanced pain transmission. The findings suggest that suppressing astrocyte signaling may enhance the effect of chronic pain drugs.

Researchers improve neuronal reprogramming by manipulating mitochondria

By expressing neuron-enriched mitochondrial proteins at an early stage, researchers achieved a four times higher conversion rate and increased the speed of reprogramming. This breakthrough may lead to developing reliable regenerative medicine therapies for brain diseases and injuries.

Reversal of glial scar tissue back to neuronal tissue through neuroregenerative gene therapy

Researchers have developed a novel neuroregenerative gene therapy that converts glial cells back into functional neurons, reversing glial scar tissue. This treatment also promotes brain recovery in mouse models of ischemic stroke and Huntington's disease, offering a promising solution to the glial scar problem.

Chronic alcohol use reshapes the brain's immune landscape, driving anxiety and addiction

Research finds that chronic alcohol exposure compromises brain immune cells, fueling anxiety and excessive drinking in mice. Boosting IL-10 signaling reverses aberrant effects, reducing anxiety-like behaviors and motivation to drink. This study provides a new framework for therapeutic intervention, targeting anti-inflammatory mechanisms.

Re-mapping taste in the brain

A new study from Stony Brook University found that the brain's 'taste map' is not composed of clusters of specialized neurons, but rather a network of overlapping and spatially distributed populations. This challenges the long-held theory of taste coding, which proposed a topographic map in the gustatory cortex for specific tastes.

Novel population of neurons identified that control binocular eye movements in 3D space

Researchers at the University of Alabama at Birmingham have identified a novel population of neurons, called saccade-vergence burst neurons (SVBNs), that control disjunctive saccades in 3D space. These findings could lead to new treatments for strabismus, a condition where eyes don't properly align.

New insight into how brain neurons influence choices

A recent study by researchers at WashU Medicine has discovered that the activity of specific brain neurons encodes the value of options and determines final decisions. The findings have significant implications for understanding decision-making in mental health conditions such as addiction, depression, and schizophrenia.

Scientists identify specific brain region and circuits controlling attention

A new study by MIT neuroscientists shows that the activity of norepinephrine-producing neurons in a single brain region, the locus coeruleus, controls both focus to ignore distractions and discipline to curb impulses. Stimulating LC activity improved attentional control tasks, while inhibiting it had the opposite effect.

Lineage tracing of direct astrocyte-to-neuron conversion for brain repair

Researchers at Jinan University successfully convert astrocytes into neurons using transgenic reporter mice and AAV viral system, providing unambiguous evidence of direct glia-to-neuron conversion. The findings dispel controversies in the field and offer a promising technology for treating neurological disorders.

Researchers find that cell adhesion proteins and a gradient of signaling molecule Sonic Hedgehog work together to create precise sorting of cells into domains. By combining experiments from biophysics, genetics, and developmental biology, the team successfully solves the puzzle of how patterns are created in developing organisms.
