behavioural observations

Extinction OF Learned behaviour
And this happens when reward is
seldom
Three stage memory model
Short term memory
Longer lived than sensory memory
Lives several seconds
With rehearsal lives longer
Working memory
Active use of both sensory and long term memory
Long term memoryLong Term Memory

Genetic memory
• A big influencer
• Fobia , Talent, even diseases can pass down from ancestors
• A Nature Neuroscience study, 2013 shows mice trained to avoid a smell passed their aversion on to their “grandchildren".
• The study was done at Emory University School of Medicine
• The results were important for phobia and anxiety research.
• The animals were trained to fear a smell similar to cherry blossom.
• Mice's offsprings and their offsprings were "extremely sensitive" to cherry blossom and would avoid the scent, despite never having experienced it in their lives.
• Changes in brain structure were also found.
Curious Case of Kim Peek
• Known as “Megasavant”Diagnosed with FG Syndrome Linked to X chromosome abnormalityCausing low muscle tone and large headCool example of brain’s plasticityHe could read with both eyes separately in
3secCould remember 98% of what he read
