Increased activity in right dorsolateral prefrontal cortex (dlPFC) may contribute to anxiety-related symptoms and has been discussed as a neurobehavioral target of anxiolytic treatments aiming to decrease avoidance behavior. Previously, we have shown that for individuals with high anxiety sensitivity excitatory right (but not left or sham) dlPFC transcranial direct current stimulation (tDCS) elicited measurable decreases in approach behavior during conflict. Here we used inhibitory tDCS over right dlPFC with concurrent excitation of left dlPFC to examine the consequences of this type of neuromodulation for approach-avoidan...

Introduction: VR immersion therapy is a practical, noninvasive and riskless technique with promising applications for rehabilitation. Preliminary studies have demonstrated its feasibility and effectiveness for various therapies targeting depression, anxiety disorders, and PTSD using exposure, relaxation, and mindfulness techniques. VR has also been shown to be an effective pain management tool for acute and chronic pain relief. These techniques tend to focus on distraction and redirecting cognitive resources from pain attention towards the VR stimuli.

Introduction: It has recently been proposed that breathing can act as an organizing hierarchical principle for neuronal oscillations throughout the brain (Herrero et al, 2018; Tort et al., 2018). Here, we propose breathing control as a natural means of neuromodulation. While brain states can influence breathing patterns (e.g. high anxiety states inducing fast breathing), the opposite possibility has attracted a great deal of interest (e.g. slow breathing inducing calm states). We test the idea that voluntary changes in breathing (e.g., deep-slow breathing) can influence neuronal excitability and rapidly promote different brain states.

Heart rate variability (HRV) biofeedback is a simple and noninvasive method for brain stimulation. This method includes paced breathing at a rate of about 6 breaths per minute (0.1Hz), which is slower and more rhythmical than natural breathing. HRV biofeedback has been used to successfully treat a wide spectrum of diseases, such as asthma, COPD, IBS, fibromyalgia, hypertension, depression, anxiety, PTSD, and insomnia (Gevirtz, 2013). It has been employed to improve performance in athletes and human operators.

Schizophrenia is associated with impairments across several cognitive functions, including reaction time, prospective time estimation, working memory, verbal learning and memory, attention, and executive functions. Transcranial alternating current stimulation (tACS) to the dorsolateral prefrontal cortex (DLPFC) is an effective non-invasive technique that may hold clinical relevance for the treatment of neuropsychiatric symptoms such as psychosis (delusions and hallucinations), depressive mood, anxiety, irritability/lability, apathy, euphoria, disinhibition, and agitation/aggression.

Anxiety disorders, including OCD and PTSD, are the most common psychiatric conditions in the United States. Yet, up to 30-40% of patients with these conditions remain resistant to existing treatments. Moreover, the underlying neural circuit abnormalities that underlie these disorders are still poorly understood, preventing us from developing novel treatments. Deep brain stimulation (DBS) is currently an FDA-approved treatment for severe, treatment-resistant Obsessive Compulsive Disorder (OCD) for which anxiety is a prominent symptom (Nuttin, et al.

Ageing is a major predicting risk factor for dementia and no treatment is currently available for this disorder. Although promising outcome has been reported for electrical stimulation on dementia, the molecular mechanisms still remain obscure. In an aged rat model, our results demonstrate that both entorhinal and perifornical stimulation enhanced spatial memory in the Morris water-maze without affecting anxiety levels. The microarray profiling showed a total of 1514 and 321 coding genes differentially expressed in the hippocampus, with a distinct pattern of signaling mechanisms involving the neurotransmission and neuropla...
