Optogenetics and deep brain stimulation neurotechnologies [PDF]

open access: yes, 2015
Brain neural network is composed of densely packed, intricately wired neurons whose activity patterns ultimately give rise to every behavior, thought, or emotion that we experience. Over the past decade, a novel neurotechnique, optogenetics that combines

A unified connectomic target for deep brain stimulation in obsessive-compulsive disorder

open access: yesNature Communications, 2020
Multiple surgical targets for treating obsessive-compulsive disorder with deep brain stimulation (DBS) have been proposed. However, different targets may modulate the same neural network responsible for clinical improvement.

Towards a computational model for stimulation of the Pedunculopontine nucleus [PDF]

open access: yes, 2009
The pedunculopontine nucleus (PPN) has recently been suggested as a new therapeutic target for deep brain stimulation (DBS) in patients suffering from Parkinson's disease, particularly those with severe gait and postural impairment [1].

Association between cognitive performance and cortical glucose metabolism in patients with mild Alzheimer's disease [PDF]

open access: yes, 2005
Background: Neuronal and synaptic function in Alzheimer's disease (AD) is measured in vivo by glucose metabolism using positron emission tomography (PET). Objective: We hypothesized that neuronal activation as measured by PET is a more sensitive index of

ABS: Scanning Neural Networks for Back-doors by Artificial Brain Stimulation

open access: yesConference on Computer and Communications Security, 2019
This paper presents a technique to scan neural network based AI models to determine if they are trojaned. Pre-trained AI models may contain back-doors that are injected through training or by transforming inner neuron weights.

Efficacy of non-invasive brain stimulation on cognitive functioning in brain disorders: a meta-analysis

open access: yesPsychological Medicine, 2020
Background Cognition is commonly affected in brain disorders. Non-invasive brain stimulation (NIBS) may have procognitive effects, with high tolerability.

Vagus Nerve Stimulation Affects Pain Perception in Depressed Adults

open access: yesPain Research and Management, 2005
BACKGROUND: Previous research suggests that vagus nerve stimulation (VNS) affects pain perception in epilepsy patients, with acute VNS decreasing pain thresholds and chronic VNS treatment increasing pain thresholds.

LTP-like cortical plasticity predicts conversion to dementia in patients with memory impairment

open access: yesBrain Stimulation, 2020
Background: New diagnostic criteria consider Alzheimer’s disease (AD) as a clinico-biological entity identifiable in vivo on the presence of specific patterns of CSF biomarkers. Objective: Here we used transcranial magnetic stimulation to investigate the

Deep brain and cortical stimulation for epilepsy [PDF]

open access: yes, 2014
Background : Despite optimal medical treatment, including epilepsy surgery, many epilepsy patients have uncontrolled seizures. In the last decades, interest has grown in invasive intracranial neurostimulation as a treatment for these patients ...

Inferring Causality from Noninvasive Brain Stimulation in Cognitive Neuroscience

open access: yesJournal of Cognitive Neuroscience, 2020
Noninvasive brain stimulation (NIBS) techniques, such as transcranial magnetic stimulation or transcranial direct and alternating current stimulation, are advocated as measures to enable causal inference in cognitive neuroscience experiments ...
