Experience reshapes cortical circuits, yet plasticity is tightly gated—high during early critical periods and increasingly constrained with maturation. Later in life, aging and Alzheimer’s disease (AD) create a growing demand to restrain network hyperactivity. Across these contexts, excitatory drive onto parvalbumin-positive fast-spiking interneurons (PVs)—shaped by synaptic organizers such as NP…

Anorexia nervosa (AN) is increasingly understood as a metabo-psychiatric disorder in which metabolic biology and neural circuit function are intrinsically intertwined. Genetic studies reveal that AN is associated with heritable metabolic traits suggesting that metabolic vulnerability contributes to the disorder. The metabolic profile of AN further shapes brain responses; endocrine signals such as…
