Brains, it has recently been argued, are essentially prediction machines. They are bundles
of cells that support perception and action by constantly attempting to match incoming …

Visual perception is one of the basic tools for exploring the world. However, in
schizophrenia, this modality is disrupted. So far, there has been no clear answer as to …

Perceptual organization (PO) refers to the processes by which visual information is
structured into coherent patterns such as groups, contours, perceptual wholes, and object …

Although visual processing impairments are common in schizophrenia, it is not clear to what
extent these originate in the eye vs. the brain. This review highlights potential contributions …

The Bayesian brain hypothesis provides an attractive unifying framework for perception,
cognition, and action. We argue that the framework can also usefully integrate interoception …

The purpose of this chapter is to demonstrate that the study of visual processing
abnormalities in schizophrenia offers a unifying perspective on the etiology, development …

Current theories of the pathophysiology of schizophrenia have focused on abnormal
temporal coordination of neural activity. Oscillations in the gamma-band range (> 25 Hz) are …

Why do brains have so many connections? The principles exposed by Andy Clark provide
answers to questions like this by appealing to the notion that brains distil causal regularities …

Clark appears to be moving toward epistemic internalism, which he once rightly rejected.
This results from a double over-interpretation of predictive coding's significance. First, Clark …

A broad neuron-centric conception of contextual modulation is reviewed and re-assessed in
the light of recent neurobiological studies of amplification, suppression, and synchronization …
