DOI: 10.1152/jn.00709.2020
Abstract: Fluctuations in the amplitude envelope of complex sounds provide critical cues for hearing, particularly for speech and animal vocalizations. Responses to amplitude modulation (AM) in the ascending auditory pathway have chiefly been described for single… read more here.

DOI: 10.1162/neco_a_01037
Abstract: Humans possess a remarkable ability to rapidly form coarse estimations of numerical averages. This ability is important for making decisions that are based on streams of numerical or value-based information, as well as for preference… read more here.

DOI: 10.1162/neco_a_01056
Abstract: While Shannon's mutual information has widespread applications in many disciplines, for practical applications it is often difficult to calculate its value accurately for high-dimensional variables because of the curse of dimensionality. This article focuses on… read more here.

DOI: 10.1523/eneuro.0211-21.2021
Abstract: Visual Abstract Molecular, anatomic, and behavioral studies show that the hippocampus is structurally and functionally heterogeneous, with dorsal hippocampus implicated in mnemonic processes and spatial navigation and ventral hippocampus involved in affective processes. By performing… read more here.

DOI: 10.3389/fnsyn.2022.888214
Abstract: The synaptic inputs to single cortical neurons exhibit substantial diversity in their sensory-driven activity. What this diversity reflects is unclear, and appears counter-productive in generating selective somatic responses to specific stimuli. One possibility is that… read more here.

Optimal Population Coding for Dynamic Input by Nonequilibrium Networks
Sign Up to like & getrecommendations! Published in 2022 at "Entropy"
DOI: 10.3390/e24050598
Abstract: The efficient coding hypothesis states that neural response should maximize its information about the external input. Theoretical studies focus on optimal response in single neuron and population code in networks with weak pairwise interactions. However,… read more here.
