Study Objectives: Actigraphy devices are used in sleep medicine. The Actiwatch 2 (Philips Respironics) was an example of a frequently used device in this field. Nevertheless, the discontinuation of this device has led to an increased necessity for the implementation of other available actigraphy methods capable of providing objective information.

- Functional MRI (fMRI) is often used to assess language function but can be inaccurate in patients with brain tumors due to cognitive issues and movement artifacts; gray matter volume (GMV) analysis offers a more stable alternative.
- This study analyzed MRI data from 22 healthy subjects and 28 patients with left-hemisphere tumors, exploring the link between GMV in language-specific brain regions and results from fMRI language lateralization tasks.
- Findings indicate that GMV in relevant brain areas is a strong predictor of language lateralization, with predictions achieving accuracy rates from 78% to 94%, suggesting that GMV analysis can enhance preoperative assessments for language function in complex cases.
Transcranial magnetic stimulation (TMS) has been found to be promising in the neurorehabilitation of post-stroke patients. Aphasia and cognitive impairment (CI) are prevalent post-stroke; however, there is still a lack of consensus about the characteristics of interventions based on TMS and its neuropsychological and anatomical-functional benefits. Therefore, studies that contribute to creating TMS protocols for these neurological conditions are necessary.

- THC and CBD are the two main compounds in cannabis, with THC causing psychoactive effects and addiction, while CBD may counteract some of these effects.
- The study aimed to investigate how THC, CBD, and their combination affect the functional connectivity of different striatal networks using fMRI in two separate placebo-controlled trials.
- Results showed that THC disrupts connectivity in various networks, while CBD can increase connectivity in the associative network and lessen THC's disruptive effects in the limbic striatum, indicating complicated interactions that may inform cannabis-related disorders and therapeutic strategies.
