Mapping the Link Between Personality and Cognitive Decline

A recent study identified three psychological profiles that influence cognitive decline and brain health in aging adults.

Profiles with high protective traits, such as a sense of purpose and openness, are associated with better cognition, mental health, and brain integrity.

Conversely, profiles with low protective traits or high levels of distress and negativity are linked to accelerated brain atrophy, poor cognition, and increased dementia risk.

Dopamine and Serotonin Drive Emotional Word Processing

A new study reveals how neurotransmitters like dopamine and serotonin are released in the brain during the processing of emotional language.

Researchers observed that emotional words—whether positive, negative, or neutral—trigger specific neurochemical patterns in distinct brain regions, including the thalamus and anterior cingulate cortex.

Surprisingly, even regions not traditionally linked to language processing, like the thalamus, exhibited neurotransmitter activity in response to emotional content.

Serotonin, GABA, and Dopamine Drive Hunger and Feeding

Researchers have identified how brain circuits and neurotransmitters regulate meal initiation, shedding light on the mechanisms of hunger and satiety.

Serotonin, a neurotransmitter that suppresses appetite, is inhibited by GABA and dopamine when hunger signals dominate, enabling meal initiation.

As feeding progresses and satiety sets in, these inhibitory signals decrease, allowing serotonin levels to rise, which suppresses further food intake.

How Alcohol Impairs the Brain’s Ability to Adapt and Learn

Alcohol use disorder (AUD) impairs cognitive flexibility by disrupting the brain’s ability to adapt to changes.

Researchers identified that chronic alcohol exposure alters the firing patterns of cholinergic interneurons (CINs) in the striatum, critical for regulating dopamine and guiding learning and behavior.

Normally, CINs exhibit a burst-pause firing pattern essential for tasks like reversal learning, where outdated behaviors are replaced with new ones.
