Researchers identified two brain networks involved in word retrieval -- the cognitive process of accessing words we need to speak. A semantic network processes meaning in middle/inferior frontal gyri, while an articulatory network in inferior frontal/precentral gyri plans speech production.

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior of our neurons and cognitive processes. Recently, researchers used modern laser microscopy techniques to observe how fluctuations in ovarian hormones shape both the structure and function of neurons in the mouse hippocampus, a brain region crucial for memory formation and spatial learning in mammals. They found that hormone fluctuations during the mouse estrous cycle, a 4-day cycle analogous to the 28-day human menstrual cycle, powerfully influence the shape and behavior of hippocampal neurons.

Researchers have conducted a clinical study to show how a woman's genetic profile provides information on which hormone treatment is most effective for in vitro fertilization (IVF). The researchers have now developed a simple oral swab test that shows which hormone therapy is the best option for IVF treatment.
