Sensory Overload May Be To BlameNew research reveals a distinct brain activity signature in children who become overwhelmed by sensory input such as noise, touch, or bright lights. Using functional MRI, scientists found that overly sensitive children show reduced activation in outward-facing sensory and motor networks while increasing activation in inward-focused networks tied to cognition and impulse control.Read More

Researchers discovered that trauma increases activity in calcium channels within a neural circuit connecting the nucleus reuniens and hippocampus, amplifying pain processing and impulsive behavior.Read More

Scientists discovered that neurons controlling appetite (AgRP neurons) interact with a brain region linked to parental care, the medial preoptic area (MPOA).Read More

Male mice who watched familiar peers attack others became more violent afterward, driven by amygdala neurons that “prime” aggression.Read More

Most incidents involve current or former intimate partners, and nearly all suicides were carried out with firearms.Read More

A new review explores whether oxytocin—a neuropeptide known to promote social bonding—can help compensate for these deficits.Read More

New research is investigating how childhood adversity rewires brain circuits that control emotion, memory, and attention, increasing the risk of impulsive and pathological aggression.Read More

Emotion & Threat, Not PsychopathyWomen who commit lethal violence rarely display psychopathy, instead acting out of provocation and perceived threats. A 15-year Swedish study of 175 cases found that about half of the women had a severe mental disorder, and these women showed slightly more short-term planning but still high emotional arousal.Read More

Researchers found that the uncinate fasciculus, a tract tied to emotion and memory, strongly correlated with dominance behaviors in squirrel monkeys. This link was especially pronounced in the right hemisphere, aligning with human findings on social aggression.Read More
