The second process is systems consolidation, occurring on a much larger scale in the brain, rendering hippocampus-dependent memories independent of the hippocampus over a period of weeks to years. Recently, a third process has become the focus of research, reconsolidation , in which previously consolidated memories can be made labile again ...
The standard model of systems consolidation largely applies to the formation of declarative memories, which include semantic, factual memories and episodic, autobiographical memories. This has been supported by case studies of human patients with MTH lesions who exhibit difficulties in remembering experiences and fact learned post-surgery ...
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
A new study offers an explanation as to how deep sleep — also known as slow wave sleep — helps support the formation of memories in the brain, which could help with preventing dementia.
Brain oedema formation is due to the breakdown of red blood cells, where haemoglobin and other contents of red blood cells are released. The release of these red blood cells contents causes toxic effect on the brain and causes brain oedema. Besides, the breaking down of blood-brain barrier also contributes to the odema formation. [13]
The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.It is the largest site of neural integration in the central nervous system, [2] and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness.
Recent studies confirm that microglia, the resident immune cell of the brain, establish direct contacts with the cell bodies of developing neurons, and through these connections, regulate neurogenesis, migration, integration and the formation of neuronal networks in an activity-dependent manner.

The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
