Benefits of exercise training in Healthy elderly
-7 weeks of aerobic exercise training
-Individuals who received the exercised displayed increased hippocampal volume
compared to those who didn’t receive training
environmental enrichment
-evidence has shown that a number if experimental conditions can facilitate stimulation
of sensory, cognitive and motor systems
Proof that environmental enrichment works in HD
-Delays onset of motor symptoms
-Improves motor and cognitive functioning
-Preserves brain volume
-Improves behaviour
-Increases weight
Week 8
Learning, Memory & Amnesia
Types of memory
The biggest categories of memory are short-term and long-term memory, based on the
amount of time memory is stored
-Long term memory: more than few minutes ago, can last for days or years
-Short term memory: working memory, responsible for storing information temporarily
and determining if it will be dismissed or transferred on to Long term memory
Types of Long term Memory
1. explicit memory!
- requires conscious thought
2. implicit memory!
- does not require conscious thought. It allows you to do things by rote
Document Summary
Individuals who received the exercised displayed increased hippocampal volume compared to those who didn"t receive training environmental enrichment. Evidence has shown that a number if experimental conditions can facilitate stimulation of sensory, cognitive and motor systems. The biggest categories of memory are short-term and long-term memory, based on the amount of time memory is stored. Long term memory: more than few minutes ago, can last for days or years. Short term memory: working memory, responsible for storing information temporarily and determining if it will be dismissed or transferred on to long term memory. Types of long term memory: explicit memory. It allows you to do things by rote. Lesions to hippocampus disrupts performance on spatial tasks. Rats placed at various locations in circular pool of murky water rapidly learn how to swim/ lesioned rats do not. Infereotemporal cortex (visual perception of objects, storing memories of visual patterns) Prefrontal cortex (working memory and other memory processes relating to memory sequencing)
