BACKGROUND: Repetitive convergent inputs to a single post-synaptic neuron can induce long-term potentiation (LTP) or depression (LTD) of synaptic activity in a spike timing-dependent manner. OBJECTIVE: Here we set a protocol of visual paired associative stimulation (vPAS) of the primary visual cortex (V1) in humans to induce persistent changes in the excitatory properties of V1 with a spike timing rule. METHODS: We provided convergent inputs to V1 by coupling transcranial magnetic stimulation (TMS) pulses of the occipital cortex with peripheral visual inputs, at four interstimulus intervals of -50/-25/+25/+50 ms relative to the visual evoked potential (VEP) P1 latency...

INTRODUCTION: Psychogenic non-epileptic seizures (PNES) are paroxysms of either altered subjective or objective manifestations that may mimic epileptic seizures (ES), without abnormal neuronal epileptiform activity. In this report, we present the case of a 39-year-old woman with PNES and functional movement disorders, who was successfully treated with neuro-guided transcranial direct current stimulation (tDCS). METHODS: We used a PET-guided tDCS approach, as a hypometabolism of the frontal region was revealed by FDG TEP scan...

BACKGROUND: Major depressive disorder (MDD) is a multifactorial disease which often coexists with cognitive deficits. Depression-induced cognitive deficits are known to be associated with aberrant reward processing, neurochemical and structural alterations. Recent studies have shown that chronic electrical stimulation of brain reward areas induces a robust antidepressant effect. However, the effects of repeated electrical self-stimulation of lateral hypothalamus - medial forebrain bundle (LH-MFB) on depression-induced cognitive deficits and associated neurochemical and structural alterations in the prefrontal cortex (PFC) are unknown...

BACKGROUND: Ambulation is an essential aspect of daily living and is often impaired after brain and spinal cord injuries. Despite the implementation of standard neurorehabilitative care, locomotor recovery is often incomplete. OBJECTIVE: In this randomized, sham-controlled, double-blind, parallel design study, we aimed to determine if anodal transcutaneous spinal direct current stimulation (anodal tsDCS) could improve training effects on locomotion compared to sham (sham tsDCS) in healthy subjects...

Ricci Hannah, Anna Iacovou, John C Rothwell
BACKGROUND: Recent studies have shown that neurophysiological outcomes of transcranial direct current stimulation (TDCS) are influenced by current flow in brain regions between the electrodes, and in particular the orientation of current flow relative to the cortical surface. OBJECTIVE: We asked whether the directional effects of TDCS on physiological measures in the motor system would also be observed on motor behaviours. METHODS: We applied TDCS during the practice of a ballistic movement task to test whether it affected learning or the retention of learning 48 h later...

BACKGROUND: Subcallosal cingulate deep brain stimulation (SCC DBS) is an experimental treatment for severe depression. Surgery is performed with awake patients and intraoperative stimulation produces acute behavioral responses in select contacts. While there have been reports on the relationship between acute intraoperative behaviors and their relation to the location of the contacts, there are no descriptions of the physiological changes that accompany them. OBJECTIVE: The present study sought to examine these physiological readouts, and their association with the anatomical substrates that generated them...

We demonstrate the feasibility of lowering the seizure threshold using a combined approach of electroconvulsive therapy and transcranial magnetic stimulation. High-frequency transcranial magnetic stimulation of the supplementary motor area shortly before each electroconvulsive treatment session resulted in a reduction of the seizure threshold by half in a male patient with a severe psychotic depressive episode of bipolar affective disorder.

BACKGROUND: Transcranial magnetic stimulation (TMS) is a non-invasive method to stimulate localized brain regions. Despite widespread use in motor cortex, TMS is seldom performed in sensory areas due to variable, qualitative metrics. OBJECTIVE: Assess the reliability and validity of tracing phosphenes, and to investigate the stimulation parameters necessary to elicit decreased visual cortex excitability with paired-pulse TMS at short inter-stimulus intervals. METHODS: Across two sessions, single and paired-pulse recruitment curves were derived by having participants outline elicited phosphenes and calculating resulting average phosphene sizes...

OBJECTIVE: To assay peripheral inter-ictal cytokine serum levels and possible relations with non-invasive vagus nerve stimulation (nVNS) responsiveness in migraineurs. METHODS: This double-blinded, sham-controlled study enrolled 48 subjects and measured headache severity, frequency [headache days/month, number of total and mild/moderate/severe classified attacks/month], functional state [sleep, mood, body weight, migraine-associated disability] and serum levels of inflammatory markers [inter-ictal] using enzyme-linked immunoassays at baseline and after 2 months of adjunctive nVNS compared to sham stimulation and suitably matched controls...

BACKGROUND: Temporal lobe epilepsy is most prevalent among focal epilepsies, and nearly one-third of patients are refractory to pharmacological intervention. Persistent cognitive and neurobehavioral comorbidities also occur due to the recurrent nature of seizures and medication-related side effects. HYPOTHESIS: Electrical neuromodulation is an effective strategy to reduce seizures both in animal models and clinically, but its efficacy to modulate cognition remains unclear...
