Expertise in medicating depression requires experience with all types of antidepressants, including several medications within each type. Likewise, electroconvulsive therapy (ECT) proficiency includes experience with each of the modern electrode placements, of which there are four. Besides traditional bilateral and right unilateral placements, ECT electrode placement includes bifrontal and left anterior right temporal (LART) placements. In comparing antidepressant drugs, clinical trials have proven few differences of statistical significance, and useful proven differences are still more unusual. Analogously, few differences have been proven between ECT electrode placements, and many reported differences can be accounted for by large differences in electrical stimulus dosage. Still, the absence of proven differences does not show that there are no useful variations. This paper reviews the meaningful differences that are generally appreciated from clinical experience and biomedical principles for ECT electrode placement as well as antidepressant drugs.

The temporoammonic pathway (TAP), the direct input from the entorhinal cortex to the hippocampus, is an important model structure for investigating synaptic plasticity. Here, we present a protocol for preparing TAP containing ex vivo slices from mice and conducting extracellular recordings of TAP inputs. We describe the specific slicing plane, an angled horizontal slice preparation, along with anatomical hallmarks for the identification of stimulation and recording electrode placement.

Background: Frailty predisposes individuals to morbidity and mortality. Increasing numbers of elderly and comorbid individuals are undergoing primary prevention implantable cardioverter defibrillator (ICD) device placement. Little is known about the association of frailty with post-device implantation outcomes.

When working with sensor-level data recorded using on-scalp neuroimaging methods such as electroencephalography (EEG), it is common practice to use two-dimensional (2D) representations of sensor positions to aid interpretation. Positioning of sensors relative to anatomy, as in the classic 10-20 system of EEG electrode placement, enables the use of 2D topographies that are familiar to many researchers and clinicians. However, when using another increasingly popular on-scalp neuroimaging method, optically pumped magnetometer-based magnetoencephalography (OP-MEG), bespoke sensor arrays are much more common, and these are not prepared according to any standard principle.

Background: Deep brain stimulation of the subthalamic nucleus (STN-DBS) effectively alleviates motor fluctuations in Parkinson's disease (PD). Optimal electrode placement and effective programming significantly influence outcomes. From a patient's perspective, DBS should relieve motor symptoms while avoiding side effects.
