gamma-Aminobutyric Acid (GABA)

Gamma-aminobutyric acid, universally known as GABA, is the primary inhibitory neurotransmitter in the central nervous system. Its main function is to reduce neuronal excitability by blocking chemical messages, which produces a calming effect. You can think of GABA as the "brakes" of the nervous system, preventing brain signals from becoming overactive and thereby controlling fear, anxiety, and stress. Many sedative and anti-anxiety medications, such as benzodiazepines, work by enhancing the effects of GABA.Proper GABA signaling is crucial for concentration and sleep, and disruptions in this system are implicated in seizures and various psychiatric disorders.

Notes

• If you happen to break something, use superglue to fix it. It will make the broken part even stronger.
• I decided to go with the ball-and-stick type, as it is easiest to color, is rigid, and looks awesome.
• The model represents the major resonance contributor.
• I oriented the model for optimal strength/waste/time compromise, but if you decide to reorient it, try to avoid placing bonds along the Z-axis, as they will be very easy to break.
• Supports removable without too much worry of damaging model if you are careful with scalpel and do of paper-sanding afterwards.
• You can use PETG as support material (don't forget to set the heatbed to 70 °C!) and PLA for the model itself (the support then come off much easier). For extra swag, use PLA support filament or PVA as supports.
• Recommended colorization is based on the Corey–Pauling–Koltun (CPK) palette (Figure 1). To quickly change colors, use the settings depicted in Figure 2.
  Alternatively, if you want to save filament and time, print the model in full-white and paint it with a permanent marker.
