Corticospinal neuron subpopulations with opposing dynamics converge to shape spinal interneuron computations

The paper identifies corticospinal neuron subpopulations with opposing activity dynamics and shows they converge to shape spinal interneuron computations during skilled movement.

Fast spiking interneurons autonomously generate fast gamma oscillations in the medial entorhinal cortex with excitation strength tuning ING-PING transitions

The paper shows fast-spiking interneurons sustain gamma oscillations via ING mechanisms, with excitation strength tuning the oscillatory regime between ING and PING.

Synchrony in Networks of Type 2 Interneurons is More Robust to Noise with Hyperpolarizing Inhibition Compared to Shunting Inhibition in Both the Stochastic Population Oscillator and the Coupled Oscillator Regimes

The paper compares the robustness of gamma oscillations in inhibitory networks with hyperpolarizing versus shunting inhibition, showing hyperpolarizing inhibition enhances synchrony robustness to noise.

Interneuronal network model of theta-nested fast oscillations predicts differential effects of heterogeneity, gap junctions and short term depression for hyperpolarizing versus shunting inhibition

The paper models interneuronal networks in the medial entorhinal cortex to show how hyperpolarizing and shunting inhibition affect theta-nested fast oscillations through gap junctions and synaptic depression.

Anomalous brain energy in old age by wavelet analysis of ERP during a Stroop task

The paper uses wavelet analysis of ERP data from a Stroop task to show that elderly with excess theta EEG activity use more energy in delta, theta, and alpha bands during stimulus categorization, potentially indicating a compensatory mechanism for cognitive demands.
