[PDF][PDF] Differential representations of prior and likelihood uncertainty in the human brain

I Vilares, JD Howard, HL Fernandes, JA Gottfried… - Current Biology, 2012 - cell.com
Background Uncertainty shapes our perception of the world and the decisions we make.
Two aspects of uncertainty are commonly distinguished: uncertainty in previously acquired …

Quantifying mesoscale neuroanatomy using X-ray microtomography

EL Dyer, WG Roncal, JA Prasad, HL Fernandes… - eneuro, 2017 - eneuro.org
Methods for resolving the three-dimensional (3D) microstructure of the brain typically start by
thinly slicing and staining the brain, followed by imaging numerous individual sections with …

[HTML][HTML] Modern machine learning as a benchmark for fitting neural responses

AS Benjamin, HL Fernandes, T Tomlinson… - Frontiers in …, 2018 - frontiersin.org
Neuroscience has long focused on finding encoding models that effectively ask “what predicts
neural spiking?” and generalized linear models (GLMs) are a typical approach. It is often …

A cryptography-based approach for movement decoding

…, MG Perich, HL Fernandes… - Nature biomedical …, 2017 - nature.com
Brain decoders use neural recordings to infer the activity or intent of a user. To train a
decoder, one generally needs to infer the measured variables of interest (covariates) from …

A reinforcement learning approach to the orienteering problem with time windows

R Gama, HL Fernandes - Computers & Operations Research, 2021 - Elsevier
… At each iteration step l, we define A l ( v ∗ l , t l ) as the set of nodes that are admissible to
be … of the sub-sequence built until step l, and of the current node v ∗ l and current time t l . …

Saliency and saccade encoding in the frontal eye field during natural scene search

HL Fernandes, IH Stevenson, AN Phillips… - Cerebral …, 2014 - academic.oup.com
The frontal eye field (FEF) plays a central role in saccade selection and execution. Using
artificial stimuli, many studies have shown that the activity of neurons in the FEF is affected by …

Toward perceiving robots as humans: Three handshake models face the turing-like handshake test

G Avraham, I Nisky, HL Fernandes… - IEEE Transactions …, 2012 - ieeexplore.ieee.org
In the Turing test a computer model is deemed to “think intelligently” if it can generate answers
that are indistinguishable from those of a human. We developed an analogous Turing-like …

[HTML][HTML] Bayesian integration and non-linear feedback control in a full-body motor task

IH Stevenson, HL Fernandes, I Vilares… - PLoS computational …, 2009 - journals.plos.org
A large number of experiments have asked to what degree human reaching movements
can be understood as being close to optimal in a statistical sense. However, little is known …

The generalization of prior uncertainty during reaching

HL Fernandes, IH Stevenson, I Vilares… - Journal of …, 2014 - Soc Neuroscience
Bayesian statistics defines how new information, given by a likelihood, should be combined
with previously acquired information, given by a prior distribution. Many experiments have …

[HTML][HTML] Generalization of stochastic visuomotor rotations

HL Fernandes, IH Stevenson, KP Kording - 2012 - journals.plos.org
Generalization studies examine the influence of perturbations imposed on one movement
onto other movements. The strength of generalization is traditionally interpreted as a reflection …
