Studying metacognition, the introspection of one’s own decisions, can provide insights into the mechanisms underlying the decisions. Here we show that observers’ uncertainty about their decisions incorporates both the entropy of the stimul…

Not from Concentrate – An Exploration of the Minds of Consumers by Combining Experimental Design of Ideas (Mind Genomics) with Artificial Intelligence (AI) Open
The origin of this specific study can be traced to the International Citrus & Beverage Conference, held in September 2023, in Clearwater, Florida.The conference brings together the various individuals involved in the world of citrus and al…

Responses to non-linguistic auditory transients in the medial geniculate nucleus are diagnostic for dyslexia in individual subjects Open
Introduction: Hypotheses concerning the neurological basis of dyslexia, a common reading disorder, include dysfunction of the magnocellular system in the brain, abnormal temporal processing, and/or deficient phonological skills. Each of th…

Segmenting the magnocellular regions in the human lateral and medial geniculate nuclei using quantitative MRI Open
Introduction: The magnocellular stream throughout the sensory systems in the brain is specialized for encoding temporal information. However, it is difficult to study in isolation because it is intermixed with other streams in cortex. Here…

Neural Dynamics during Binocular Rivalry: Indications from Human Lateral Geniculate Nucleus Open
When two sufficiently different stimuli are presented to each eye, perception alternates between them. This binocular rivalry is conceived as a competition for representation in the single stream of visual consciousness. The magnocellular …

Identifying the layers in the human lateral geniculate nucleus using quantitative and functional MRI Open
Segregating the magnocellular (M) and parvocellular (M) layers of the human lateral geniculate nucleus (LGN) is difficult yet remains an important goal because the LGN is the location where the two streams are anatomically disjoint. Previo…

Evaluating Quantitative and Functional MRI As Potential Techniques to Identify the Subdivisions in the Human Lateral Geniculate Nucleus Open
Segmenting the magnocellular (M) and parvocellular (P) divisions of the human lateral geniculate nucleus (LGN) has been challenging yet remains an important goal because the LGN is the only place in the brain where these two information st…

A specialized channel for encoding auditory transients in the magnocellular division of the human medial geniculate nucleus Open
We test the hypothesis that there exists a generalized magnocellular system in the brain optimized for temporal processing. In the visual system, it is well known that the magnocellular layers in the lateral geniculate nucleus (LGN) are st…

The magnocellular division of the human medial geniculate nucleus preferentially responds to auditory transients Open
The medial geniculate nucleus (MGN), the auditory relay in the thalamus, is composed of three anatomical subdivisions: the ventral, dorsal and medial or magnocellular division. The functional differences among these nuclei have not been st…

Dyslexia linked to profound impairment in the magnocellular medial geniculate nucleus Open
The neurological basis of dyslexia, a common reading disorder, remains unclear but is hypothesized to be caused by either dysfunction of the magnocellular system in the brain, abnormal temporal processing, and/or deficient phonological ski…

An entropy model of decision uncertainty reveals that attention influences decisions but does not alter appearance Open
Metacognition, the introspection of one’s own decisions, can inform our understanding of decision mechanisms. Here we show that decision uncertainty reflects the entropy of the psychometric function. To test this novel model, we measured u…

A three-response task reveals how attention alters decision criteria but not appearance Open
Whether attention alters appearance or just changes decision criteria continues to be controversial. When subjects are forced to choose which of two equal targets, one of which has been pre-cued, has a higher contrast, they tend to choose …

Cortical and subcortical dynamics during binocular rivalry Open
Binocular rivalry occurs when the two eyes are presented with conflicting stimuli. These stimuli compete for perception such that the observer can only perceive one stimulus at a time. We sought to measure the interplay among visual cortex…

Distinguishing Hemodynamics from Function in the Human LGN Using a Temporal Response Model Open
We developed a temporal population receptive field model to differentiate the neural and hemodynamic response functions (HRF) in the human lateral geniculate nucleus (LGN). The HRF in the human LGN is dominated by the richly vascularized h…

Larger Auditory Cortical Area and Broader Frequency Tuning Underlie Absolute Pitch Open
Absolute pitch (AP), the ability of some musicians to precisely identify and name musical tones in isolation, is associated with a number of gross morphological changes in the brain, but the fundamental neural mechanisms underlying this ab…

The Flash-Lag, Fröhlich and Related Motion Illusions Are Natural Consequences of Discrete Sampling in the Visual System Open
The Fröhlich effect and flash-lag effect, in which moving objects appear advanced along their trajectories compared to their actual positions, have defied a simple and consistent explanation. Here, I show that these illusions can be unders…
