version: "1.0.0" name: region-atlas description: TVB default connectivity region names and indices for the 76-region Hagmann parcellation. Use when setting region-specific parameters (stimulus weights, x0, model.I), selecting regions by name, or mapping neuroscience labels to TVB indices. Triggers on region, index, label, V1, V2, M1, hippocampus, atlas, parcellation.

TVB Default 76-Region Atlas

The default Connectivity.from_file() loads the Hagmann parcellation (76 regions). Region names and indices are:

 0: medial orbitofrontal (l)     1: medial orbitofrontal (r)
 2: frontal pole (l)            3: frontal pole (r)
 4: insula (l)                  5: insula (r)
 6: temporal pole (l)           7: temporal pole (r)
 8: superior temporal (l)       9: superior temporal (r)
10: parahippocampal (l)        11: parahippocampal (r)
12: amygdala (l)              13: amygdala (r)
14: precentral (l)             15: precentral (r)       ← M1
16: postcentral (l)            17: postcentral (r)      ← S1
18: superior parietal (l)      19: superior parietal (r)
20: supramarginal (l)          21: supramarginal (r)
22: lingual (l)                23: lingual (r)
24: pericalcarine (l)          25: pericalcarine (r)    ← V1
26: cuneus (l)                 27: cuneus (r)
28: lateral occipital (l)      29: lateral occipital (r) ← V2 area
30: precuneus (l)              31: precuneus (r)
32: rostral anterior cingulate (l) 33: rostral anterior cingulate (r)
34: caudal anterior cingulate (l)  35: caudal anterior cingulate (r)
36: posterior cingulate (l)    37: posterior cingulate (r)
38: isthmus cingulate (l)      39: isthmus cingulate (r)
40: hippocampus (l)            41: hippocampus (r)
42: fusiform (l)               43: fusiform (r)

56: pars triangularis (l)     57: pars triangularis (r)
58: pars orbitalis (l)        59: pars orbitalis (r)
60: lateral orbitofrontal (l) 61: lateral orbitofrontal (r)
62: transverse temporal (l)   63: transverse temporal (r)  ← A1
64: superior frontal (l)      65: superior frontal (r)
66: frontal pole (l)          67: frontal pole (r)  [duplicate label]
68: thalamus proper (l)       69: thalamus proper (r)

Common neuroscience labels → TVB indices

Label	TVB region name	Index
V1	pericalcarine (l)/(r)	24, 25
V2	lateral occipital (l)/(r)	28, 29
A1	transverse temporal (l)/(r)	62, 63
M1	precentral (l)/(r)	14, 15
S1	postcentral (l)/(r)	16, 17
DLPFC	caudal middle frontal (l)/(r)	52, 53
hippocampus	hippocampus (l)/(r)	40, 41
amygdala	amygdala (l)/(r)	12, 13
ACC	caudal anterior cingulate (l)/(r)	34, 35
PCC	posterior cingulate (l)/(r)	36, 37
thalamus	thalamus proper (l)/(r)	68, 69

Safe lookup pattern

python

conn = connectivity.Connectivity.from_file()
conn.speed = 4.0
conn.configure()
labels = conn.region_labels  # list of 76 strings
# Find index by partial name match
v1_idx = [i for i, l in enumerate(labels) if "pericalcarine" in l]
# Use to set stimulus weights
stim_weights = numpy.zeros((76, 1))
stim_weights[v1_idx, 0] = 1.0

Critical warnings

Never use invented labels like "rHC" or "rCCP" — they do not exist in the atlas.
Always verify with conn.region_labels before assigning region-specific parameters.
Left = even-ish indices (0,2,4...), Right = odd-ish — but NOT guaranteed. Always look up by name.
