A sparse coding model of V1 produces surround suppression effects in response to natural scenes
(Georgia Institute of Technology, 2013-05-08)
Recent electrophysiology research has made significant advancements toward revealing the neural basis of early visual processing. The brain is optimized to draw conclusions from natural scenes, and models of the human ...
The Neurochemical Mobile: Analysis of Dynamic Interactions between Six Neurotransmitters
(Georgia Institute of Technology, 2013-05-08)
A mobile, typically seen in an infant’s crib, is an eloquent representation of the balance between multiple items. The neurochemical mobile is a tool used to visualize the balance between six major neurotransmitters in the ...
Multi-task learning for neural image classification and segmentation using a 3D/2D contextual U-Net model
(Georgia Institute of Technology, 2020-05)
We present a 3D/2D Contextual U-Net model and apply it to segment and classify samples from a heterogeneous mouse brain dataset obtained via X-ray microtomography, which spans 4 distinct brain areas: Striatum, Ventral ...
A Highly-Scalable Automated Rodent Training Platform
(Georgia Institute of Technology, 2019-05)
Background: Rodent training is a necessary but time-consuming process that often requires the development of computer-based training systems to automate the process of administering a food or water reward in return for the ...
Characteristic Neural Firing Profiles in Different Hippocampal Subfields for Successful and Unsuccessful Memory
(Georgia Institute of Technology, 2020-05)
Memory is our ability to encode, store, retrain, and subsequently recall information and
past experiences. Different areas of the brain are responsible for different aspects of memory,
including the hippocampus which enables ...
Quasi-Periodic Patterns of Resting-State Brain Activity in Individuals with Idiopathic Hypersomnia and Narcolepsy
(Georgia Institute of Technology, 2020-05)
The brain’s overall organization of its networks is often studied through its functional connectivity, defined as the spatiotemporal dependency of neuronal activity in anatomically separated regions. Altered functional ...
Implicit awareness during skilled motor learning and the implications for rehabilitation
(Georgia Institute of Technology, 2020-05)
Motor skills and sequential motor learning are essential in our day to day lives, however, little behind the brain regions involved is known. This means that when someone has a deficiency in their motor skills or their ...
Pruritic Activity and Neurogenic Inflammation with S. aureus δ-toxin in Atopic Dermatitis
(Georgia Institute of Technology, 2021-05)
This study investigates how toxins secreted from Staphylococcus aureus, such as δ-toxin, can produce pruritis and initiate neurogenic inflammation to help characterize the cutaneous
neural reaction to S. aureus colonization ...
Stress effects on the ability to learn statistical regularities about our world
(Georgia Institute of Technology, 2020-05)
Stress, a common feature of everyday life, has been demonstrated in numerous studies to profoundly impact memory function, particularly functions dependent on the hippocampus. The impacts of acute stress on statistical ...
The Impact of Sleep on Quasi-Periodic Patterns During Working Memory Tasks
(Georgia Institute of Technology, 2022-05)
Quasi-periodic patterns (QPPs) are a form of low-frequency neural activity that include the interactions of both default mode and task positive networks. As this brain activity occurs constantly in our brains, they are ...
