Christopher Bergland, How Does Your Brain Learn Through Trial and Error? Problem-solving and critical thinking can rewire the orbitofrontal cortex (OFC), Psychology Today, Mar. 6, 2016. In a groundbreaking discovery, neurocientists at the University of California, Berkeley, have captured brain images of active learning in real-time by photographing the brains of
Long-range orbitofrontal and amygdala axons show divergent patterns of maturation in the frontal cortex across adolescence
The adolescent transition from juvenile to adult is marked by anatomical and functional remodeling of brain networks. Currently, the cellular and synaptic level changes underlying the adolescent transition are only coarsely understood. Here, we use two-photon imaging to make time-lapse observations of long-range axons that innervate the frontal cortex in
Rule learning enhances structural plasticity of long range axons in frontal cortex
Rules encompass cue-action-outcome associations used to guide decisions and strategies in a specific context. Subregions of the frontal cortex including the orbitofrontal cortex (OFC) and dorsomedial prefrontal cortex (dmPFC) are implicated in rule learning, although changes in structural connectivity underlying rule learning are poorly understood. We imaged OFC axonal projections
Cell-Type-Specific Control of Brainstem Locomotor Circuits by Basal Ganglia
The basal ganglia (BG) are critical for adaptive motor control, but the circuit principles underlying their pathway-specific modulation of target regions are not well understood. Here, we dissect the mechanisms underlying BG direct and indirect pathway-mediated control of the mesencephalic locomotor region (MLR), a brainstem target of BG that is
Early maternal separation impacts cognitive flexibility at the age of first independence in mice
Early life adversity is associated with increased risk for mental and physical health problems, including substance abuse. Changes in neural development caused by early life insults could cause or complicate these conditions. Maternal separation (MS) is a model of early adversity for rodents. Clear effects of MS have been shown
