BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Hunger, Fear, and the Brain’s Hidden Switch to Turn Off Chronic Pain

Chronic pain affects nearly 50 million Americans, yet new research reveals the brain may have an internal switch that can turn it down. Scientists identified a group of neurons in the brainstem that regulate long-term pain by integrating signals related to hunger, fear, and thirst.

Chronic Pain Linked to Neuron Overactivity in the Brainstem

A new study reveals that neurons in the brainstem respond very differently to acute versus chronic pain, potentially explaining why some pain persists long after injury. In acute pain, neurons in the medullary dorsal horn reduce their activity through a natural “braking” system involving A-type potassium currents, helping limit pain signals.

Brain-Body Links in Emotion and Health

Researchers have developed D-PSCAN, a novel imaging technique that enables high-resolution, minimally invasive observation of the brainstem’s nucleus tractus solitarii (NTS) in living animals. The NTS, a vital relay for signals from organs via the vagus nerve, plays a key role in emotion regulation and overall mental health.

New Neuron Types Discovered in Brainstem’s Sound Processing Center

Researchers have identified and mapped diverse cell types in the cochlear nucleus, the brainstem region responsible for processing sound. Using advanced molecular techniques, they uncovered distinct and newly identified cell types that process specific sound features, such as sharp noises or pitch changes.

Brainstem Plays Vital Role in Visual Attention

Researchers highlights the locus coeruleus (LC), a small brainstem region, as critical in enhancing visual sensory processing through its production of norepinephrine. In the study scientists used optogenetics to activate these specific neurons in non-human primates, significantly improving their performance in a visual attention task.

Brainstem Atrophy Is Linked to Extrapyramidal Symptoms in Frontotemporal Dementia

Patients who suffer from frontotemporal dementia with extrapyramidal symptoms have brainstem atrophy and reduced metabolic activity in specific brain regions compared to those with FTD without extrapyramidal symptoms.
