Laura Sacerdote introduces Jacobi models of the neuronal membrane potential, with inhibitory jumps that are dependent on the state of the membrane.
Giuseppe D’Onofrio presents Jacobi model numerical simulations to learn how they describe neuronal firing rate dynamics and inhibition, beyond classical leak-integrate-and-fire predictions.
Cristina Zucca explains the problem of detecting when a signal changes trend, and describes a method to identify the moment when change begins in response to a motor cue from macaque premotor cortex LFP data.
Given a perturbation to a neural system of a given size, how far do you need to go find another system that is decorrelated from such perturbation? Dante Chialvo presents correlation lengths and scaling properties as a means to probe borderline regimes of critical behavior in cortex.
Electrical synapses are quick means to sync neurons, and Sebastián Curti compares differences in rat versus mouse mesencephalic trigeminal nucleus neurons suggesting D-type potassium currents as a key to coupling potentials’ waveforms.
Following evidence that Purkinje cells (PC) change activity of deep cerebellar nuclear (DCN) neuron targets, Christine Pedroarena addresses whether modulation of PC background activity could allow for flexible selection of specific PC ensembles to control DCN neurons.
Roseli Wedemann discusses the motivations to generalize neural network models of associative memory which are continuous and have dissipative, multidimensional neurons.
Andrés Pomi employs probabilistic mappings to illustrate how the associative storage of ensemble activity may lead to Bayesian computation via statistical learning.
Pawel Herman connects lexical processing with olfaction through an application of distributional semantics of text corpus statistics, noting the topical association between olfactory perception and the lexicon.
Cornelius Schwartz addresses how to get quick texture information as kinematic patterns unfold from tactile vibration signals, raising analogies between the rodent whisker and human fingertips.
Tadeo Neyén Segovia presents preliminary results on a study on chromatic induction, the perceptual change of color appearance due to a chromatic surround, modeling its effects in relation to visual receptive field parameters.
Jonathan Victor addresses the problem of spatial source location in odorant fields, making use of information theory measures in combination with the effects of active sensing strategies.
Francisco Cervantes Constantino uses decoder models to extract formant dynamics of human speech from the electroencephalogram (EEG) of listeners, addressesing whether decodability helps their behavior under challenging multispeaker scenarios.
Alessandra Lintas presents a neural trait approach based on EEG and functional near-infrared spectroscopy (fNIRS) tools to characterize greed and selfishness variables during play of the Ultimatum game.
Ángel Caputi presents a logical decision-making study which shows that errors and delays are introduced as one deals with negations and also with exclusive disjunction (xor) operations.
Elvira Di Nardo addresses approximation solutions to the first passage problem, where events are triggered as a random variable first crosses some threshold, relevant in the context of single neuron and small network modeling.
Alessandro Villa shows findings that working memory training increases risk-taking attitudes of attention deficit hyperactivity disorder individuals, and discusses the functional significance of cerebellar contributions to working memory training changes.
Barry Richmond presents sinusoidal phase temporal coding in the monkey striatum as it predicts rewarding outcomes. By contrast, their frontal lobe corticostriatal projections appear to operate on intensity rate coding at the population level, hence on markedly distinct neural codes.
Diego Gallo talks on the role of the dopaminergic system in regulating low gamma-band cortical EEG activity, showing how dopamine antagonists slow down these rhythms.
Santiago Castro studies the directionality of phase shifts in low gamma-band EEG activity, showing how leading frontal to parietal shifts in wakefulness may disappear during sleep and with ketamine or scopolamine preparations.
Joaquín González discusses the relation of gamma oscillations in olfactory cortex with the phases of breathing, as they may help inhibit neural assemblies thus creating opportunities for sparse processing of odorants.
Tatyana Turova presents work on randomly grown networks of neurons, and discusses their connectivity properties and transitions as graph processes, aiming to understand activity propagations throughout.
Based on magnetic resonance imaging data, Lucas Díaz seeks to simplify the probabilistic distributions of cortical anatomical variables, finding a key parameter in the mismatch between an area’s cortical volume and the product of its surface and thickness.
Eyisto Aguilar proposes a new metric to determine the critical state of the brain. Measuring the loss of spatial correlations with distance may serve to characterize the critical state of a network in optical imaging datasets.
