Except as provided in Rule 841, a defendant who intends to introduce expert evidence relating to a mental disease or defect or any other mental condition of the defendant bearing (1) on the issue of guilt, or (2) in a capital case, on the issue of punishment, shall file with the clerk of courts not later than the time required for filing an omnibus pretrial motion provided in Rule 579 a notice of the intention to offer this expert evidence, and shall serve a copy of the notice and a certificate of service on the attorney for the Commonwealth.

Within 10 days after receipt of the defendant's notice of the insanity or mental infirmity defense, or notice of expert evidence of a mental condition, or within such other time as allowed by the court upon cause shown, the attorney for the Commonwealth shall file and serve upon defendant's attorney, or the defendant if unrepresented, written notice of the names and addresses of all witnesses the attorney for the Commonwealth intends to call to disprove or discredit the defendant's claim of insanity or mental infirmity, or mental disease, defect, or other mental condition.

(F) FAILURE TO CALL WITNESSES

No adverse inference may be drawn against the defendant, nor may any comment be made concerning the defendant's failure to call available witnesses with regard to the insanity or mental infirmity defense, when such witnesses have been prevented from testifying by reason of this rule, unless the defendant or the defendant's attorney shall attempt to explain such failure to the jury.
