Yes, this episode was similar to the X-Files where Scully got an implant at the base of her neck as well.  However, this story was years before that plot was introduced to that show.  There was also that worm they used in The Wrath of Kahn, which is similar.  A good listen.  I liked how she was the only one who believed about the aliens until her next door neighbor convinced her own husband and the main character's husband.
