When a familiar environment is reshaped, the grid cell spatial code is dynamically anchored to recently encountered boundaries and changes throughout exploration with the specific movement history of the navigator.
The classical experimental paradigm of "enriched environments" is repositioned as a tool to address the question of how behavioral activity and the environment contribute to specific differences between individuals.
Combining GABA with fMRI measurements in the human brain uncovers distinct suppression mechanisms that optimize perceptual decisions through learning and experience-dependent plasticity in the visual cortex.

LSD induces a pattern of changed global brain connectivity characterized by hypo-connectivity in associative areas and hyper-connectivity across sensory and somatomotor areas that is dependent on the serotonin 2A receptor.

Mathematical models with experimental validation show that chloride transporters in the cell membrane, and not negatively charged impermeant molecules, generate the driving force used by GABA receptors to silence neurons.
Dopamine is able to ensure that neural networks maintain critical features of their output, such as synchrony of neuron firing, by directly increasing coupling strength to ensure robust output is maintained.
Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

Pet1 neurons actively maintain cardiorespiratory tone and dynamic range in mouse neonates and critically support the recovery response to apneas, informing brain findings in the sudden infant death syndrome.
