KembaraXtra-Psychology – Bromocriptine
Bromocriptine is a dopamine agonist medication derived from ergot alkaloids. It mimics the action of dopamine in the brain and is commonly used in the treatment of Parkinson’s disease, where dopamine deficiency contributes to motor symptoms. It is also prescribed for certain hormonal conditions such as amenorrhoea and infertility because it suppresses prolactin secretion from the anterior pituitary gland. By targeting dopamine receptors, bromocriptine demonstrates the close relationship between neurochemistry and both motor and endocrine regulation.

KembaraXtra-Psychology – Bruce Effect
The Bruce effect refers to a phenomenon observed in mice in which a recently mated female fails to maintain pregnancy when exposed to the scent of an unfamiliar male. The effect is triggered by pheromones present in the urine of the strange male, which disrupt prolactin secretion and prevent implantation of the fertilized ovum. It was first described by British reproductive biologist Hilda Margaret Bruce in 1959. This phenomenon illustrates the powerful role of olfactory cues and pheromonal communication in reproductive biology.P

KembaraXtra-Psychology – Brujería
Brujería refers to a form of folk healing or spiritual practice found in Spanish-speaking Caribbean and southern United States communities. Closely related to rootwork or folk magic traditions, it often involves rituals, herbal remedies, and spiritual beliefs intended to influence health, relationships, or fortune. In psychological contexts, such practices are studied as examples of culturally embedded belief systems that influence perception, coping, and mental health.

KembaraXtra-Psychology – Brunswik Faces
Brunswik faces are simplified schematic drawings of human faces used in perceptual and cognitive research. Developed by psychologist Egon Brunswik, these stylized faces allow researchers to systematically vary features such as eye spacing, nose size, and mouth curvature. By manipulating these variables, psychologists can study perceptual discrimination, categorization, and the processes involved in social judgment.

KembaraXtra-Psychology – Brute Force Algorithm
A brute force algorithm is a problem-solving method that systematically examines every possible solution before selecting the optimal one. While feasible for small-scale problems, brute force approaches become impractical for highly complex tasks such as the travelling salesman problem or chess, due to the enormous number of possible combinations. This concept highlights computational limits in both artificial intelligence and human cognition.

KembaraXtra-Psychology – Bruxism
Bruxism is the habitual grinding or clenching of teeth, which may occur during wakefulness or during Stage II non-REM sleep. It is often associated with stress, anxiety, or sleep disorders and can lead to dental damage, jaw pain, and headaches. Bruxism illustrates the interaction between psychological tension and motor activity.

KembaraXtra-Psychology – BSE (Bovine Spongiform Encephalopathy)
BSE, commonly known as mad cow disease, is a progressive and fatal neurodegenerative disorder affecting cattle. It is widely believed to be caused by prions—misfolded proteins that induce abnormal folding in normal brain proteins. In humans, exposure has been linked to variant Creutzfeldt–Jakob disease. The condition highlights the vulnerability of neural tissue to protein misfolding disorders.

KembaraXtra-Psychology – Buccal
The term buccal refers to structures relating to the cheek or mouth. In medical and psychological contexts, it often describes routes of drug administration (such as buccal tablets) or anatomical features involved in speech and feeding.

KembaraXtra-Psychology – Burnt Odour
Burnt odour is classified as one of the primary odour qualities in certain early olfactory classification systems. It resembles the smell of tar or charred material and reflects attempts to categorize olfactory perception into fundamental sensory types.

KembaraXtra-Psychology – Buridan’s Ass
Buridan’s ass is a philosophical example illustrating decision-making paralysis. A hypothetical donkey placed exactly between two identical bales of hay is unable to choose and therefore starves. The scenario symbolizes approach–approach conflict and highlights the limitations of purely rational decision rules when options are equally attractive.
