Phase-specific Activation Induces Latent Connectivity Changes

A recent paper provides rare causal evidence that phase-specific stimulation during beta oscillation bursts lead to transient changes in effective (latent) connectivity. This finding and its potentially widespread implications are discussed in our paper Womelsdorf T, Hoffman K (2018) Latent Connectivity: Neuronal Oscillations Can Be Leveraged for Transient Plasticity. Current Biology. 28(16):R879-R882..

Inter-areal neural routing states emerge and switch during oscillatory bursts and with attention

We have a new major finding published at Neuron. We found that spiking in different areas (ACC, Striatum, LPFC) engage in ~20ms wide correlations, and that this coordinated activity has systematic time lags that correspond to the anatomical connectivity. These ‘baseline routing states’ are amplified during beta bursts, and switch directionality (between ACC and PFC) […]

Computational Properties of Prefrontal Cortex – Workshop

We hosted a superb 2018 CPPC (Computational Properties of Prefrontal Cortex) Workshop at Vanderbilt. The workshop attracted more than 60 emerging and established (neuro-)scientists about how the prefrontal cortex works – See the program and more at the www link CPPC2018. This year had special sessions on value-based decision making and uncertainty, social cognition, functional […]

Updating of Attentional Priorities is Causally Supported by ACC and Striatum

A long-standing open question is how brain circuits learn what information is behaviorally relevant and should be attended. We have a new key insight to this question published in the paper “Adaptive Reinforcement Learning is causally supported by Anterior Cingulate Cortex and Striatum” (Neuron, pdf). We found that brief 0.3 s electrical stimulation at the […]
