Memory and the brain: what's right and what's left?

Article Abstract:

The existing body of knowledge on memory and other cognitive processes is founded on a number of studies on brain-damaged patients. Initial information about the neural bases of memory can be traced from the study on patient H.M., who underwent bilateral excision of his medial temporal lobes (MDL). This and other studies on amnesiacs provided evidence for the role of MDL in memory formation. However, evidence for the prefrontal cortex's association with memory processing came from lesion studies. The advent of brain imaging has also contributed to the knowledge about memory.

Micrasterias cells as model system for research on morphogenesis

Article Abstract:

Normal micrasterias morphogenesis requires continuous nucleus-dependent protein synthesis throughout the development process. The formation of three lobes and the synthesis of mRNA and protein occur independent of nuclear control. Calcium is an essential feature in morphogenesis. An increase in Ca2+ influx due to accumulation of calcium channels in the prospective growth areas leads to generation of an electric field. This leads to a localized deposition of cell wall materials. Calcium also affects the cortical actin network responsible for localized vesicle fusion.

Craniofacial morphogenesis: a meeting in memory of Peter Thorogood

Article Abstract:

Scientists held a meeting on embryonic craniofacial development in September, 1999, in honor of Peter Thorogood. Thorogood was a specialist in craniofacial development at the Institute of Child Health, University College London who died in a climbing accident in the Swiss Alps.
