Memory Loss & Alzheimer’s Disease

“In brief, memory loss may be defined as the loss of, or inaccessibility to, previously learned or acquired information over time. Individuals with memory loss may also experience difficulties learning new material. Memory loss is sometimes referred to by various terms including amnesia, forgetting, memory decay, memory decline, or memory impairment (see Loring, 1999). Pathology/lesions in a diversity of brain regions and systems have been associated with memory loss, and in particular, damage to the brain’s temporal lobes and a part of the brain known as the hippocampus…”

Forgetting, Decay Theory, Interference…

“When we take in new information, a certain amount of time is necessary for changes to the nervous system to take place – the consolidation process – so that it is properly recorded. During this period information is moved from short term memory to the more permanent long term memory.

The brain consists of a vast number of cells called neurons, connected to each other by synapses. Synapses enable chemicals to be passed from one neuron to another. These chemicals, called neurotransmitters, can either inhibit or stimulate the performance of neurons. So if you can imagine a network of neurons all connected via synapses, there will be a pattern of stimulation and inhibition.  It has been suggested that this pattern of inhibition and stimulation can be used as a basis for storing information.  This process of modifying neurons in order form new permanent memories is referred to as consolidation (Parkin, 1993)…”

The Drilldown Method: A Strategy for Learning Faster

“During the yearlong pursuit, I perfected a method for peeling those layers of deep understanding faster. I’ve since used it on topics in math, biology, physics, economics and engineering. With just a few modifications, it also works well for practical skills such as programming, design or languages.

Here’s the basic structure of the method:

  1. Coverage
  2. Practice
  3. Insight

I’ll explain each stage and how you can go through them as efficiently as possible, while giving detailed examples of how I used them in actual classes…”
