Electrodes placed in which location are likely to produce the highest rates of self–stimulation by an animal?

Median Forebrain bundle

Explanation:

The Median Forebrain bundle is a pathway in the brain that consists of a variety of fibres that serves as a way or means of connection between the brainstem, the hypothalamus and also the basal forebrain.

When electrodes are placed in the median forebrain bundle, the hormone dopamine tends to be released resulting in feelings or sensations of pleasure due to the stimulation of the median forebrain bundle.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

they absorb it i think

not sure
