**Understanding Split-Brain Patients: Visual Field and Response Ability**

In certain neurological conditions, such as split-brain patients, interactions between the two hemispheres of the brain are disrupted. This can have a profound effect on how such patients perceive and respond to visual stimuli. Here's a multiple-choice scenario to examine the capabilities of split-brain patients when visual information is presented to the right visual field.

**Question:**

If you were to show something to the right visual field of a split-brain patient, they would be able to:

- **Option 1:** Not be able to say what they saw, but could draw it with their left hand.
- **Option 2:** Say what they saw.
- **Option 3:** Not be able to say what they saw, nor be able to draw it at all.
- **Option 4:** Not be able to say what they saw, but could draw it with their right hand.

This exercise aims to provide insight into the functional localization of brain activities and the specific challenges faced by split-brain patients. Understanding their responses can illuminate the complexities of brain functions and inter-hemispheric communications.

Educators can use this example to illustrate concepts related to brain lateralization and the consequences of severed corpus callosum, often associated with split-brain patients.

### The Libet Experiment and the Readiness Potential

The Libet Experiment found that the start of the Readiness Potential:

- ⭕ Occurred after participants reported they had the will to move to move their wrist.
- ⭕ Preceded when participants reported they had the will to move ONLY but not before they moved their wrist.
- ⭕ Preceded when participants reported they had the will to move AND before they moved their wrist.
- ⭕ Preceded when participants actually moved ONLY but not before reporting the will to move their wrist.

This question pertains to the famous Libet Experiment, which investigated the relationship between human movement and conscious intention. The Readiness Potential is a measure of the brain's preparatory activity before voluntary movement. Understanding the sequencing of these events can shed light on the mechanisms of conscious will and motor actions. 

The correct answer highlights a key aspect of how our brain signals readiness for movement even before we become consciously aware of our intention to move.
