Background: Obsessive-compulsive disorder (OCD) is a psychiatric condition defined by the presence of obsessions, compulsions, or both. It has a lifetime prevalence of 2%-3% and causes significant impairment in social and work functioning, as well as a reduced quality of life. Treatment includes pharmacotherapy and psychotherapy, but a significant number of patients fail to respond to treatment. Deep brain stimulation has shown to be a safe and effective procedure for severe, chronic, treatment-resistant OCD, and several surgical targets have been proposed for treatment, including the nucleus accumbens, the anterior limb of the internal capsule, the subthalamic nucleus, the globus pallidus, and the bed nucleus of stria terminalis.
Objectives: To report the first Italian case series of patients who underwent DBS of 2 distinct targets for OCD: nulceus accumbens and bed nulceus of stria terminalis.
Methods: Four patients underwent DBS of the nulceus accumbens, and 4 patients underwent DBS of the bed nucleus of stria terminalis.
Results: Six patients showed a significant improvement in OCD symptoms.
Conclusions: DBS of these 2 structures is a safe and effective procedure for the treatment of severe, refractory OCD.

Background: Previous studies have shown that neurons in the Bed Nucleus of the Stria Terminalis (BNST) respond to stress and play a key role in mental health. However, the cellular bases of BNST in adolescent depression remain elusive.
Methods: Male C57BL/6 mice were randomly assigned to the control (Ctrl) or chronic unpredictable stress (CUS) groups.

Background: Effects of subthalamic nucleus deep brain stimulation (STN-DBS) on neuropsychiatric symptoms of Parkinson's disease (PD) remain debated. Sensor technology might help to objectively assess behavioural changes after STN-DBS.
Case Presentation: 5 PD patients were assessed 1 before and 5 months after STN-DBS with the Movement Disorders Society Unified Parkinson's Disease Rating Scale part III in the medication ON (plus postoperatively stimulation ON) condition, the Montreal Cognitive Assessment, the Questionnaire for Impulsive-Compulsive Behaviors in Parkinson's Disease Rating Scale present version, the Hospital Anxiety and Depression Scale and the Starkstein Apathy Scale.

Theta oscillations of the mammalian amygdala are associated with processing, encoding and retrieval of aversive memories. In the hippocampus, the power of the network theta oscillation is modulated by basal forebrain (BF) GABAergic projections. Here, we combine anatomical and computational approaches to investigate if similar BF projections to the amygdaloid complex provide an analogous modulation of local network activity.

The bed nucleus of the stria terminalis (BNST) is involved in feeding, reward, aversion, and anxiety-like behavior. We identify BNST neurons defined by the expression of vesicular glutamate transporter 3, VGluT3. VGluT3 neurons were localized to anteromedial BNST, were molecularly distinct from accumbal VGluT3 neurons, and co-express vesicular GABA transporter (VGaT).

The parabrachial nucleus (PB), located in the dorsolateral pons, contains primarily glutamatergic neurons that regulate responses to a variety of interoceptive and cutaneous sensory signals. One lateral PB subpopulation expresses the Calca gene, which codes for the neuropeptide calcitonin gene-related peptide (CGRP). These PB neurons relay signals related to threatening stimuli such as hypercarbia, pain, and nausea, yet their inputs and their neurochemical identity are only partially understood.
