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

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 …

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
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
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
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
Generalization studies examine the influence of perturbations imposed on one movement
onto other movements. The strength of generalization is traditionally interpreted as a reflection …
