In the present study, clinical interview, Visual Evoked Potentials, psychological tests, TRH test, plasmatic MHPG dosage were investigated in 30 depressed patients with major depressive disorders. All the explorations were realised before and after 28 days of an antidepressant treatment. Thanks to analysis we found out the value of psychological tests. The study of evoked potentials brings to light the existence of electrophysiological variables, subordinate to the clinical state. On the contrary, "TRH Test" does not give us any useful indication, and plasmatic MOPEG dosage, although it confirms the existence of two groups of depressed patients, does not suggest any relationship with evolutive types.

K1 channels enable myelinated axons to transmit spikes reliably without spiking ectopically.

Action potentials (spikes) are regenerated at each node of Ranvier during saltatory transmission along a myelinated axon. The high density of voltage-gated sodium channels required by nodes to reliably transmit spikes increases the risk of ectopic spike generation in the axon. Here we show that ectopic spiking is avoided because K1 channels prevent nodes from responding to slow depolarization; instead, axons respond selectively to rapid depolarization because K1 channels implement a high-pass filter.

Objectives: Hearing loss is associated with increased cognitive decline and incident dementia in older adults. Given the rapidly rising incidence of dementia, management of modifiable risk factors such as hearing loss, is essential to mitigate the impact on the individual and society in general. In this narrative review, we discuss the current state-of-art with respect to studying cognitive function before and after cochlear implantation in the elderly population.

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.

Aggression is commonly associated with increased experiences of peer rejection and maladaptive social information processing biases throughout development. Little is known about the neural correlates of peer rejection that might underlie social information processing biases, and whether these neural correlates are common or different across early- and mid-adolescents on a continuum of aggression. Using the Cyberball task, we examined mediofrontal theta (4-7 Hz) event-related EEG spectral power during conditions of explicit and ambiguous social exclusion in 117 participants (57 early adolescents, ages 10-12 years, and 60 mid-adolescents, ages 14-16 years).

Objective: This study assessed the effects of transcranial direct current stimulation (tDCS) on cue reactivity and craving for game-related cues using event-related potentials (ERPs) in internet gaming disorder (IGD) patients.
Methods: At baseline, a series of game-related and neutral pictures were shown to both IGD and healthy controls (HCs) while ERPs were recorded. Late positive potentials (LPP) were used to investigate cue reactivity.
