0

Who is HM?

He had severe temporal lobe epilepsy
Underwent bilateral medial surgery

1

Epileptic seizures?

Sudden excitation in groups of neurons with a loss of inhibitory potential

2

What is released in excitatory synapse?

Glutamate

3

What is released in a inhibitory synapse?

GABA

4

What is temporal lobe epilepsy?

Recurrent unprovoked seizures from medial or lateral temporal lobes

5

What are the 2 types of temporal epilepsy?

Simple- feel a change but no loss of awareness
Complex- loss of awareness

6

Hippocampal sclerosis?

Neuron cell death, increase in goal cells
Occurs early in life
Past infections, tumours

7

Declarative memory is?

Conscious access to information learned previously

8

What does HM tell us about memory?

Temporal lobes are essential
Especially for anterograde memories
And that there is a difference between declarative and procedural memories

9

What is the hippocampus' role?

Learning and consolidating novel information

10

Consolidation theory?

After consolidation info can be retrieved without hippocampus involvement

11

Multiple trace theory?

Always involves hippocampus system ( for episodic)
