34 Neuron Subtypes Linked to Addiction

Researchers identified 34 distinct subtypes of medium spiny neurons (MSNs) in the nucleus accumbens, a brain region crucial for reward and addiction. This discovery challenges previous views of MSNs as a homogeneous group, revealing a complex diversity with potential implications for understanding addiction and developing targeted therapies. The study suggests these findings may be conserved across species, offering insights into human brain function.

Dehydration Impairs Attention in Middle-Aged Adults

Mild dehydration can impair sustained attention in middle-aged and older adults, though it doesn't affect other cognitive functions. The study involved 78 adults, ages 47 to 70, and assessed their hydration levels and cognitive performance. Results showed that dehydration, common during typical daily activities, reduced attention span over 14 minutes. The findings highlight the need for regular hydration to maintain cognitive function in older adults.
