question 66

Multiple Choice

The Focus on Neuroscience box, "Brain Reward When Making Eye Contact with Attractive People," described an fMRI study in which participants were scanned while looking at photographs of different faces, some looking directly at the viewer (eye-contact) and some looking away (non-eye-contact) . What did the results of this study show?

• A)When we make eye contact with an attractive person, the brain area that is associated with the expectation of a reward shows increased activity.
• B)When we make eye contact with any person, whether they are attractive or not, both the orbital frontal cortex and the amygdala show low levels of activation.
• C)When we view faces of attractive people averting their gaze and not making eye contact the ventral striatum becomes highly active.
• D)When we make eye contact with an attractive person, the brain area that is associated with the expectation of a reward shows decreased activity.

RAM

Random Access Memory, a type of computer memory that can be accessed randomly, any byte of memory can be accessed without touching the preceding bytes.

Forward Bias

In electronics, a condition where the positive end of a voltage source is connected to the p-type material and the negative end to the n-type material of a semiconductor, allowing current flow.

Bipolar Transistor

A transistor that operates like a switched diode. It contains base, emitter, and collector terminals and can have NPN or PNP biasing.

Non-Contact Throttle Position Sensors

Sensors that detect the position of the throttle valve without direct contact, using magnetic or optical technology to improve response and reliability.
