Page 3: Timing

Roberts (1965)

• Activity cycle slightly less than 24 hours in constant dim light

• Restoring visual cues produces a gradual shift back to correct time.

• Entrainment: light acts as a zeitgeber (resets 24 hour clock)

Page 18: Timing

Scalar Timing

• How do remember times scale to real time?– Error is relative

• error is a constant proportion of the timed interval

• called scalar timing

– So, if the memory of time is • just right, k = 1.0

• too early, k < 1.0

• too late, k > 1.0

Page 19: Timing

Dopamine• Clock Speed Theory

– Agonists (speed clock, left-shifted, K < 1.0)– Antagonist (slowed clock, right shifted, K >1.0)

• Threshold Theory– Agonists lower threshold (impulsivity)– Antagonist increase threshold (sluggish)

• Striatum Theory– D1 affects general motivation (number of responses)– D2 affects response timing (time of peak)

Page 20: Timing

Some Data

Page 21: Timing

Parkinson's

• Dopamine D1 depletion causes reduced motivation to respond (decrease in amount of responding)

• Dopamine D2 depletion causes a leftward shift (late timing)

• External stimulus might replace internal cues from the striatum
