The reading passage argues that brain scan lie detector is more accurate than conventional polygraphs in three matters. On the other hand, the lecturer refutes the ideas presented in the reading by proposing several counterarguments.

First of all, the lecturer contends that true statements can be misidentified as lies. He explains that holding information activates the same brain part as lying. Also, the brain part is activated even when a person is embarrassed. Therefore, it can not always accurately evaluate the reliability of a statement by scanning the brain parts. This directly challenges the author’s claim that the new method can clearly state whether a person is lying or not.

Second, the professor argues that results can not be interpreted in an objective manner by using the novel device. This is because each person’s brain functions distinctively, making it impossible to be assessed objectively. Therefore, there are no clear criteria for interpreting the results. This contradicts the reading’s claim that brain scan lie detector can judge test results fairly.

Finally, the speaker refutes the idea that the mechanism made it more difficult for a subject to intentionally trick the test. He points out that recent studies show that subjects can mask their brain activity by thinking of difficult problems such as math equations. In addition, their brain acted like they were lying whenever they read a fictional novel. These points undermine the reading’s argument that the new polygraph makes a subject challenging to trick the test.

The reading passage argues that the brain scan lie detector is more accurate than conventional polygraphs in three matters.

You need to either add an article before "brain" or else say brain scan lie detectorS in plural.

On the other hand, the lecturer refutes the ideas presented in the reading by proposing several counterarguments.

First of all, the lecturer contends that true statements can be misidentified as lies.

He explains that holding (?) information activates the same brain part as lying.

I'm not quite sure what is meant by "holding information" Could you mean "withholding information"

Also, the brain part is activated even when a person is embarrassed.

Therefore, it can not always accurately evaluate the reliability of a statement by scanning the brain parts.

This directly challenges the author’s claim that the new method can clearly state whether a person is lying or not.

Second, the professor argues that results can not be interpreted in an objective manner by using the novel device.

I would probably say new device instead of novel device, just because for me "novel" has a more fun connotation which is clearly not the case here.

This is because each person’s brain functions distinctively, making it impossible to be assessed objectively.

Therefore, there are no clear criteria for interpreting the results.

This contradicts the reading’s claim that brain scan lie detector can judge test results fairly.

Again, either add an article before brain or make detector plural.

Finally, the speaker refutes the idea that the mechanism made it more difficult for a subject to intentionally trick the test.

He points out that recent studies show that subjects can mask their brain activity by thinking of difficult problems such as math equations.

In addition, their brain acted like they were lying whenever they read a fictional novel.

These points undermine the reading’s argument that the new polygraph makes ~~a subjec~~it challenging for a subject to trick the test.
