Dissociation between area TE and rhinal cortex in accuracy vs. speed of visual categorization in rhesus monkeys Open

Bing Li, Kaleb A. Lowe, Samarth Chandra, Gang Chen, Mark A. G. Eldridge , et al. · 2024

In real-world vision, objects may appear for a short period, such as in conjunction with visual search. Presumably, this puts a premium on rapid categorization. We designed a visual categorization task cued by briefly presented images to s…

Specific Changes in Arabidopsis thaliana Rosette Lipids during Freezing Can Be Associated with Freezing Tolerance Open

Hieu Vu, Sunitha Shiva, Thilani Samarakoon, Maoyin Li, Sujon Sarowar , et al. · 2022

Chemistry Biology

While the roles of a few specific lipids in plant freezing tolerance are understood, the effect of many plant lipids remains to be determined. Acclimation of plants to non-freezing cold before exposure to freezing temperatures improves the…

Frontal eye fields in macaque monkeys: prefrontal and premotor contributions to visually guided saccades Open

Kaleb A. Lowe, Wolf Zinke, Joshua D. Cosman, Jeffrey D. Schall · 2022

Psychology Biology

Neuronal spiking was sampled from the frontal eye field (FEF) and from the rostral part of area 6 that reaches to the superior limb of the arcuate sulcus, dorsal to the arcuate spur when present (F2vr) in macaque monkeys performing memory-…

Neural Correlates of Multidimensional Perceptual Decision Making in Macaque Frontal Eye Field Open

Kaleb A. Lowe, Thomas R. Reppert, Jeffrey D. Schall · 2020

Computer science Psychology Economics

Perceptual decision making tasks have a long history in the visual sciences to understand the organization of visual processing and to develop sophisticated models of response times in stochastic accumulator model frameworks. However, thes…

Leaf Lipid Alterations in Response to Heat Stress of Arabidopsis thaliana Open

Sunitha Shiva, Thilani Samarakoon, Kaleb A. Lowe, Charles Roach, Hieu Vu , et al. · 2020

Chemistry Biology

In response to elevated temperatures, plants alter the activities of enzymes that affect lipid composition. While it has long been known that plant leaf membrane lipids become less unsaturated in response to heat, other changes, including …

Selective influence and sequential operations: A research strategy for visual search Open

Kaleb A. Lowe, Thomas R. Reppert, Jeffrey D. Schall · 2019

Psychology Computer science

We discuss the problem of elucidating mechanisms of visual search. We begin by considering the history, logic, and methods of relating behavioral or cognitive processes with neural processes. We then survey briefly the cognitive neurophysi…

Induction of Shape Selectivity in Macaque Frontal Eye Field Dissociates Perceptual and Motor Processing Stages of Visual Search Open

Kaleb A. Lowe, Jeffrey D. Schall · 2019

Psychology Computer science

Neurons in frontal eye field (FEF) respond to visual stimulation, before eye movements, and both. These responses differentiate whether or not a stimulus is a saccade target. This differentiation, or target selection, is stimulus-locked fo…

Sequential Operations Revealed by Serendipitous Feature Selectivity in Frontal Eye Field Open

Kaleb A. Lowe, Jeffrey D. Schall · 2019

Computer science Psychology Biology

Neurons in macaque frontal eye field contribute to spatial but typically not feature selection during visual search. Using an innovative visual search task, we report a serendipitous discovery that some frontal eye field neurons can develo…

Selective Influence and Sequential Operations: A Research Strategy for Visual Search Open

Kaleb A. Lowe, Thomas R. Reppert, Jeffrey D. Schall · 2019

Computer science Psychology

We introduce conceptually and empirically a powerful but underutilized experimental approach to dissect the cognitive processes supporting performance of a visual search task with factorial manipulations of singleton-distractor identifiabi…

Effects of visual search target-distractor congruence on stimulus-response mapping in macaques: Saccade timing and vigor Open

Thomas R. Reppert, Kaleb A. Lowe, Jeffrey D. Schall · 2018

Psychology Medicine Biology

The general goal of this work is to develop a visual search task for macaque monkeys that allows decomposition of functionally distinct processing stages through the analytic logic of separate modifiability. Monkeys are trained to search f…

Functional Categories of Visuomotor Neurons in Macaque Frontal Eye Field Open

Kaleb A. Lowe, Jeffrey D. Schall · 2018

Computer science Psychology

Frontal eye field (FEF) in macaque monkeys contributes to visual attention, visual-motor transformations and production of eye movements. Traditionally, neurons in FEF have been classified by the magnitude of increased discharge rates foll…
