Disclosed are methods of treating depression, mania, post-traumatic stress disorder (PTSD), and various other neurologic conditions using synaptic pathway training. Methods of synaptic pathway training include, generally, achieving a favorable treatment result by activating a synaptic pathway using a pharmacologic agent, such as treating refractory symptoms of depression with ketamine, following by potentiation of the favorable result by repeatedly stimulating the activated pathway. Stimulation of a synaptic pathway may be achieved by intrinsic means, such as performance of cognitive exercised, or extrinsic means, such as by delivery of a sensory stimulus to the patient, placing a potential voltage difference across the brain or a brain region, or by placing the brain or a brain region in a magnetic field.

Method for treatment of depression using synaptic pathway training

Tracer ammunition is disclosed and includes a projectile having a body; a chamber in the body having a front end and a rear end, the rear end of the chamber being open; an aperture at a rear end of the body providing an opening to the open end of the chamber; and a tracer material disposed within the chamber, wherein the tracer material is configured to combust when ignited and emit optical energy through the aperture as a result of the combustion process. The tracer material may be configured to include a rear-facing surface having a concave contour to aid in directivity of light output from the tracer material.

Projectile tracer

A detachable gun barrel assembly having an adapter for threaded engagement with the receiver and a barrel dimensioned for affixation to the adapter. The adapter has a mating end section which threadedly engages the receiver V-threads and a receiving end section having square internal threads. The mating end section has a limit flange at its innermost end. The receiving end section has a larger internal diameter to form an internal flange or stop between sections. The barrel has an alignment section which inserts into the mating end section and contacts the limit flange. A securing section of the barrel is provided with a square external thread to engage the receiving end section and contact the internal flange. The elongated barrel is provided with an external shoulder which contacts the receiving end section upon affixation of barrel to adapter thereby providing a number of stops to maintain barrel alignment.

Detachable gun barrel assembly

A modified barrel for an automatic weapon having a muzzle attachment including a gas expansion chamber to permit use of a short barrel while delivering the normal pressure to the gas drive mechanism. The attachment delivers the gas pressure via a conduit from the chamber to an exit port coupled to the gas drive mechanism of the weapon.

Muzzle attachment for barrel of gas-operated weapon

A gas chamber fixture having attachment to the barrel of a gas-operated weapon wherein the barrel and the weapon are mechanically attached by means of a mating mortise and tenon. A bead is received in recesses formed in the adjacent surfaces of the mortise and tenon to facilitate rotation during attachment and provide sealing engagement of the joined parts. A gas passage between barrel and chamber is provided through the bead to provide the driving force to the drive mechanism located in the chamber.

Attachment for affixation to the barrel of a gas operated weapon

A sight mount for interchangeable sighting devices which provides adjustable eye relief and improved stability. The base, affixed to the receiver, is provided with parallel guideways to receive a slide support. Midway on the base is a vertically movable block which frictionally engages the slide support to lock it into position at the desired distance from the eye. A separate slide support is used for each scope for ease of interchange.

Sight mount providing adjustable eye relief

A boresight for determining the accuracy of a gunsight wherein a cartridge-shaped housing is dimensioned to fit within the gun chamber. A laser is contained in the housing. A switch is positioned in the end surface of the boresight housing to be contacted by the bolt face of the gun. The switch contains an indentation to receive the firing pin when the bolt face contacts the switch to activate the laser and illuminate a distant spot.
