Brain Genes

 

Biochemistry: Receptor Gene
Bit Description Detail
11 Locus of attachment ID This three-character Locus ID
(representing "organ," "tissue," and "site")
 is the neuron stimulated by the receptor.
See brain structure for more details
12
13
14 ? ?
15 Chemical received  The chemical that binds to the receptor and triggers its 'firing'
16 Threshold  The level of chemical that must be present before the
neuron bearing the bound receptor will 'fire'
17 Nominal  The amount to stimulate the locus if the chemical does not exceed the threshold.
18 Gain  The amount to stimulate the locus if the chemical does exceed the threshold
19 Output  First digit Whether increased stimulus decreases output
(as opposed to increasing it)
Second digit Digital: new value = nominal + (gain * R)
Analog: new value = nominal + (((amount - threshold) * gain/255) * R)
where R is either 1 or -1 (see op - output below).

 

 

Biochemistry: Emitter Gene
Bit Description Detail
11 Locus of
attachment ID		 This three-character Locus ID (representing "organ," "tissue," and "site")
 is the neuron stimulated by the receptor. See brain structure for more details
12
13
14 Chemical Emitted The chemical emitted when the chemical emitter binds to a cell in the brain
15 Threshold  The level of chemical that must be present before the neuron bearing the bound receptor will fire
16 Sample Rate A value used to calculate output
17 Gain  Whether the emitter is analog or digital determines how it is combined with the current signal level and the threshold to calculate output 
18 Emitter Type Whether to invert input signal, whether to clear source byte after reading
Digital: output = Gain if Signal > Threshold
Analog: output = (signal - Threshold) * Gain

 

 

Stimulus Gene
Bit Description Detail
11 stimulus The trigger for the reaction
12 significance The amount the significance neurone is nudged by
13 sensory neurone The sensory lobe neurone providing input
14 intensity The amount to nudge the input neurone by
15 features Additional features:
01 = Modulate using sensory signal
02 = Add offset to neurone (e.g. word)
03 =  Detected even if asleep
16 chemical 1 emitted Up to four allowed, blank ones marked 00

see chemical list for details
17 amount of chemical 1 emitted
18 chemical 2 emitted
19 amount of chemical 2 emitted
20 chemical 3 emitted
21 amount of chemical 3 emitted
22 chemical 4 emitted
23 amount of chemical 4 emitted

 

 

Instinct Gene
Bit Description Detail
11 Triggers The trigger type 01 Drive One of the 13 drive chemicals
02 Source Object, words 16 - 31
03 Verb words 00 - 11
05 General Sensory see brain function page for list
12 The actual trigger for the gene, varies depending on type  - see above
13 The second trigger type
(If more than one trigger is set then consider a boolean  'AND' connecting them)
14 Second actual trigger
15 Third trigger type
16 Third actual trigger
17 Actions The specific action that the Creature should perform when 11/13/Both are true (words 00 - 11)
18 Chemicals The chemical to inject when the conditions are all met
19

The amount of chemical 19 to inject

 

 

Lobes Gene
Bit Description Detail Section
11 Starting X position The location of the upper left of the
lobe on a  64 x 48 grid		 General
12 Starting Y position
13 Width Size of lobe in neurones (a rectangle)
14 Height
15 Perception
lobe link		 00 = no
01 = yes
02 = mutually exclusive
16 nominal threshold A neurone will fire if its state rises above the threshold Cell Body
17 leakage rate  
18 rest state  
19  input gain lo-hi  
20 state rule Used to calculate the new state of every neurone each "tick"
(about 4 times a second)
21 winner takes all This means that all but the strongest-firing cell in the lobe is suppressed.
This function can be used to decide which action or object wins the vote
(in Decision and Attention lobes)
22 source lobe The source lobe for the dendrite connections for these dendrites Dendrite
