: Overweight and obesity are global public health problems associated with chronic disease and mental health. Physical activity (PA) is essential throughout a person's life; an active lifestyle helps people to live healthier lives and improve their functional and mental abilities, such as executive function (EF). This systematic review aimed to analyze the evidence on the effects of PA on EF in overweight and/or obese adults (≥18 years old).

Article Synopsis
  • The study examines how different access protocols to palatable food (PF) influence binge-like eating behaviors in adolescent male Wistar rats, which may be relevant for understanding human obesity.
  • Three groups of rats were given varying access to PF—continuous, intermittent, and weekend access—over a period of six weeks, followed by a withdrawal period.
  • Results showed that restricted access led to increased binge-like eating, with the intermittent access group exhibiting the highest levels of binge eating, highlighting how food availability affects consumption patterns during adolescence.

Aging is generally associated with a decline in important cognitive functions that can be observed in EEG. Physical activity in older adults should be considered one of the main strategies to promote health and prevent disease in the elderly. The present study aimed to systematically review studies of EEG activity and cognitive function changes associated with physical activity in older adults.

The CB2 cannabinoid receptor has been found in brain areas that are part of the reward system and has been shown to play a role in food intake regulation. Herein, we conducted a systematic review of studies assessing the role of the CB2 receptor in food intake regulation. Records from the PubMed, Scopus, and EBSCO databases were screened, resulting in 13 studies that were used in the present systematic review, following the PRISMA guidelines.

Article Synopsis
  • * Increased cannabis use during adolescence raises concerns about its impact on the ECS and neurogenesis, which is the process of generating new neurons in the brain.
  • * The article emphasizes the importance of maintaining a balanced ECS to prevent adverse effects on neural development, which can alter behaviors like stress, anxiety, learning, and memory.

One of the most important things in the field of adult hippocampal neurogenesis (AHN) is the identification of the newly generated cells. The immunodetection of thymidine analogs (such as 5-Bromo-2'-deoxyuridine (BrdU)) is a standard technique used for visualizing these newly generated cells. Therefore, BrdU is usually injected in small animals intraperitoneally, so the thymidine analog gets incorporated into dividing cells during DNA synthesis.

Brainwaves amplitude obtained from electroencephalography (EEG) has been well-recognized as a basis for cognitive capacity, memory, and learning on animals and humans. Adult neurogenesis mechanism is also linked to memory and learning improvement. Traditionally, researchers used to assess learning and memory parameters in rodent models by behavioral tasks.
