Strings and Booleans

Strings are text — wrapped in quotes. Booleans are True or False.

python
neuron_type = 'excitatory'  # string
brain_region = "hippocampus"  # also string — both ' and " work

is_refractory = True   # boolean — neuron is in refractory period
is_spiking = False     # boolean — not currently firing

Strings hold text. Booleans hold yes/no values.

Booleans come from comparisons:
`python
5 > 3 → True
10 == 10 → True (== means 'equal to')
7 != 7 → False (!= means 'not equal to')
V > -55 → True if voltage is above threshold
`

= means 'assign'. == means 'compare'. Common mistake: if x = 5 is wrong. Use if x == 5.
