The Neural Computations In The Caudate Nucleus For Reward-Biased Perceptual Decision-Making
… outcome options. To begin to investigate what computations are performed by the brain, particularly in the basal ganglia, we trained monkeys to perform a reward-biased visual motion direction discrimination task and performed single-unit extracellular recordings in the caudate nucleus, the …

Assessing the neural computations supporting predictions of form and meaning in speech comprehension
… The second aim was to investigate the neural computational mechanisms that combine predictions (priors) with sensory input during spoken sentence processing. Chapter 1 provides a general introduction and overview of the behavioural, cognitive, neural, and computational research …

Strong and weak principles of Bayesian machine learning for systems neuroscience
Neuroscientists are recording neural activity and behaviour at a rapidly increasing scale. This provides an unprecedented window into the neural underpinnings of behaviour, while also pushing the need for new techniques to analyse and model these large-scale datasets. Inspiration for such tools can …

Design of optoelectronic activation, local memory and weighting circuits for Compact Integrated Optoelectronic Neural (COIN) Co-processor
The Compact Integrated Optoelectronic Neural (COIN) Co-processor, a prototype of artificial neural network implemented in hybrid optics and optoelectronic hardware, aims to implement a multi-layer neural network algorithm by performing parallel and efficient neural computations. In this thesis, we …

Monoaminergic Signaling in the Human Brain: New Insights
… and norepinephrine uniquely contribute to neural computations throughout the forebrain, influencing attention, learning and decision-making. However, resolving these monoaminergic signals at physiologically and behaviorally relevant spatiotemporal scales in the human brain have been …

Neurobiology of incremental speech comprehension
… to keep track of the temporal dynamics of the neural computations involved. To do this, I used combined electroencephalography and magnetoencephalography (EMEG) to record neural activity with millisecond resolution and analyzed the recordings in source space using univariate and/or multivariate …

The dynamics of invariant object and action recognition in the human visual system
… high temporal resolution data to understand neural computations.

smart-Kage: Autonomous behavioural phenotyping in a rodent home-cage environment
… of animal behaviour together with underlying neural computations from which it emerges. Whereas great progress has been made in technology used to record neural activity, studies of behaviour have thus far lacked an equally methodical and concerted development that could support/enable …

The Effect of Sensory Experience and Movement Observation on Motor Adaptation to Novel Force Perturbations
… that influence subsequent motor command; the neural computations underlying such a learning process are not well understood. In this thesis, I aimed to further understand how people incrementally update their predictive motor control in novel haptic environments as a function of sensation …

Ultra-Fast and Multi-Dimensional Face Processing in a New Face Area
… representation for face motion using canonical neural computations. Finally, we found that MD responds with much a shorter delay than any other face areas. It starts providing facial information as early as 30 ms. We then performed connectivity experiments to study where MD sends such fast …

Neural Computation Through Synaptic Dynamics in Serotonergic Networks
… be a fundamental determinant of population-level computations and behavioral output of the brain, yet their role in neuromodulatory circuits is relatively under-explored. First, I developed and validated a set of likelihood-based inference tools to quantify the dynamics of synaptic ensemble …
