Existence of Interhemispheric Inhibition between Foot Sections of Human Primary Motor Cortices: Evidence from Negative Blood Oxygenation-Level Dependent Signal

open access: yesBrain Sciences, 2021
Interhemispheric inhibition (IHI) between the left and right primary motor cortices (M1) plays an important role when people perform an isolated unilateral limb movement. Moreover, negative blood oxygenation-level dependent signal (deactivation) obtained

Rational Neural Network Controllers [PDF]

open access: yesarXiv, 2023
Neural networks have shown great success in many machine learning related tasks, due to their ability to act as general function approximators. Recent work has demonstrated the effectiveness of neural networks in control systems (known as neural feedback loops), most notably by using a neural network as a controller.

Assessment of glutamatergic synaptic transmission and plasticity in brain slices: relevance to bioelectronic approaches

open access: yesBioelectronic Medicine, 2019
Background Glutamatergic neurons represent the largest neuronal class in the brain and are responsible for the bulk of excitatory synaptic transmission and plasticity. Abnormalities in glutamatergic neurons are linked to several brain disorders and their

Effective connectivity during autobiographical memory search

open access: yesBrain and Behavior, 2020
Introduction We used dynamic causal modeling (DCM) to examine effective connectivity during cued autobiographical memory (AM) search in a left‐hemispheric network consisting of six major regions within the large network of brain regions recruited during ...

Correspondence of categorical and feature‐based representations of music in the human brain

open access: yesBrain and Behavior, 2021
Introduction Humans tend to categorize auditory stimuli into discrete classes, such as animal species, language, musical instrument, and music genre. Of these, music genre is a frequently used dimension of human music preference and is determined based ...

Local circuit allowing hypothalamic control of hippocampal area CA2 activity and consequences for CA1

open access: yeseLife, 2021
The hippocampus is critical for memory formation. The hypothalamic supramammillary nucleus (SuM) sends long-range projections to hippocampal area CA2. While the SuM-CA2 connection is critical for social memory, how this input acts on the local circuit is

A Review of Recurrent Neural Networks: LSTM Cells and Network Architectures

open access: yesNeural Computation, 2019
Recurrent neural networks (RNNs) have been widely adopted in research areas concerned with sequential data, such as text, audio, and video. However, RNNs consisting of sigma cells or tanh cells are unable to learn the relevant information of input data ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Brain imaging and machine learning reveal uncoupled functional network for contextual threat memory in long sepsis

open access: yesScientific Reports
Positron emission tomography (PET) utilizes radiotracers like [18F]fluorodeoxyglucose (FDG) to measure brain activity in health and disease. Performing behavioral tasks between the FDG injection and the PET scan allows the FDG signal to reflect task ...

Preclinical Models of Overwhelming Sepsis Implicate the Neural System that Encodes Contextual Fear Memory

open access: yesMolecular Medicine, 2016
Long-term sepsis survivors sustain cryptic brain injury that leads to cognitive impairment, emotional imbalance and Increased disability burden. Suitable animal models of sepsis, such as cecal ligation and puncture (CLP), have permitted the analysis of ...
