Thalamocortical interactions shape hierarchical neural variability during stimulus perception

no code implementations15 Mar 2024 Adrià Tauste Campo, Antonio Zainos, Yuriria Vázquez, Raul Adell Segarra, Manuel Álvarez, Gustavo Deco, Héctor Díaz, Sergio Parra, Ranulfo Romo, Román Rossi-Pool

While feedforward interactions from VPL and area 3b were favored by neurons within specific Fano factor ranges, neural variability in area 1 was invariant to the incoming pathways.

Demixed Principal Component Analysis

no code implementations NeurIPS 2011 Wieland Brendel, Ranulfo Romo, Christian K. Machens

Standard dimensionality reduction techniques such as principal component analysis (PCA) can provide a succinct and complete description of the data, but the description is constructed independent of the relevant task variables and is often hard to interpret.

Dimensionality Reduction

Linear readout from a neural population with partial correlation data

no code implementations NeurIPS 2010 Adrien Wohrer, Ranulfo Romo, Christian K. Machens

We compare the discrimination thresholds read out from the population of recorded neurons with the discrimination threshold of the monkey and show that our method predicts different results than simpler, average schemes of noise correlations."
