Adjustable headpiece with anatomical markers and methods of use thereof

An apparatus comprising:

• a headpiece configured to be worn on a head of a user and comprising a first single receptacle configured to receive and retain both a first energy source and a first portion of a second energy source therein and a second receptacle configured to receive and retain a second portion of the second energy source;
• a U-shaped bridging medium at least partially disposed within the first single receptacle and aligned with the first portion of the second energy source;
• an adjustment mechanism disposed on the headpiece and configured to move at least one of the first single receptacle or the second receptacle within a 3 dimensional space about the user's head;
• and
• at least three markers, each marker being physically coupled to the headpiece and configured to be aligned with at least one anatomical structure of the user's head, wherein a first marker is a nasion marker, a second marker is an inion marker, and a third marker is a first tragus marker, and wherein the apparatus is configured so that a position of at least one of the first energy source or the second energy source can be adjustably aligned relative to a target region of neural tissue in the user's head by aligning the at least three markers with their designated anatomical structures with the adjustment mechanism.

An apparatus comprising:

• a headpiece configured to be worn on a head of a user and comprising at least a first receptacle configured to receive and retain a first energy source;
• a U-shaped bridging medium at least partially disposed within the first receptacle;
• at least one adjustment mechanism disposed on the headpiece and configured to move the first receptacle within a 3 dimensional space about the user's head;
• at least one marker coupled to the headpiece and configured to be aligned with at least one anatomical structure of the user's head, wherein a position of the first energy source can be adjustably aligned to a target region of neural tissue in the user's head by aligning the at least one marker with its designated anatomical structure with the at least one adjustment mechanism;
• and
• a transduction mechanism configured to assess a characteristic of the apparatus and control any part of the apparatus.
